Getting Started

Hi.
Im trying to execute the program in mine laptop both Mac and windows, but, has been imposible, the program report the following "java.lang.NullPointerException" error.
What can I do to fix ti?

Is it possible to import Scopus' finding for Cluster Mapping by CitNetExplorer software?

Dear Ludo, is it possible to save the list of publications of a citation pattern?
thanks in advance
matteo

Can someone please give some hints on how I might get started providing
CitNetExplorer both with (1) data on publications and (2) with data on citation relations between publications. I am using Pubmed and I would like to work out how to export data to construct a publication file and a citation file. Is this possible? What do I need to do in order to get started?

Hi, can you use data from Pubmed / Medline? If so, how should I export it?
Thanks
Richard

Your tool looks incredible. It looks like an incredibly useful tool to conduct an initial literature survey in support of a structured literature review. I am going to download and see if it might be helpful. Nice work. Brilliant, actually!!

Hi.i get some data from web of science but the citnetexplorer give me error. Error while reading web of science file.....file is not valid.heeeeelp me😰

Hi,
I'm literally just getting started. I worked through the tutorial and all was fine. However, on trying to run my own example, I keep getting the following error message:
"An unexpected error has occurred (java.lung.NullPointerException). The program will be terminated."
Any ideas what I'm doing wrong?!
Thanks in advance for your help!

Hi, loving the software so far. I am however coming into trouble trying to include referenced data of the works I've included in my analysis. Is there a way for the software to pull references in the articles and include them in the mapping analysis without me having to go into each article and extract these references and include them manually? Thanks

Hi!
Thanks for developing this tool!
I have met the same problem: "An unexpected error has occurred (java.lang.NullPointerException). The program will be terminated".
I had already excluded early accessed files, I tried to download CitNet again and reinstalled java 8, but the problem remains. I've just get open the app once, using my first search.
Could you help me?
Thanks a lot!

I have found my mistake and could import citations from Web of science. Their formatting is too specific to be replicated with a reasonable amount of efforts, so I guess CitNetExplorer does not only "allow citation networks to be imported directly from the Web of Science database", but also *needs* it. Any idea about another software that does the same with self-cropped data?
Thanks anyway for the hard work.
Philippe

how can i find a specific research field with citnetexplorer? If i download all data from one person?

Hello,
Thanks for developing CitNetExplorer. I'm getting started with it and I find it very useful.
I have and issue when importing data from Web of Science. I get this message: "An unexpected error has occurred (java.lang.NullPointerException). The program will be terminated". I found that excluding one of the publications (I pasted the register in this comment), the issue was solved. I identified the problematic publication by trial and error.
I've got this issue with other data, so it would be very helpful to know how to identify problematic publications. Thanks!
Note: following other comments, I excluded Early Access publications, but the issue stills.

We propose a definition of payment innovations and present the evolution of their introduction in the Polish market, indicating the impact of legal regulations and the critical character of the new FinTech phenomenon. The analysis that we conducted was based on the results of a survey which obtained responses from 24 commercial banks representing almost the entire Polish retail banking sector based on the number of personal accounts maintained. The study helped to determine the main elements of the strategies implemented by banks in Poland. It also revealed the methods for competing in the area of payment services utilized by the banks, with innovative services as one of the leading elements. The results of the study indicated that there was a significant differentiation of applied strategies depending on a bank's size. In the case of larger banks, the main motivation for introducing payment innovations was characteristic of an offensive strategy, and for smaller banks - more often a defensive one. We also proposed a theoretical model for using the specific nature of payment innovations to build customer relationships and to apply cross-selling.

Hello,
I used to make maps via cit net explorer. after a long time this week I tried to use it but ı took a notification like this: "can not find DOI number...". After taking this notification, I read the getting started tutorial again. I got the same data set from wos. I made all the steps as in the tutorial. but again I got the same message "can not find DOI number...".Please let me know how I can solve it.
Thanks
Burcu

Running the current version on Debian 9.11 I get an exception:
$ java -jar CitNetExplorer.jar
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
at org.pushingpixels.substance.internal.utils.SubstanceColorUtilities.getDefaultBackgroundColor(SubstanceColorUtilities.java:758)
This is using

OpenJDK 64-Bit Server VM (build 11.0.4+11-post-Debian-1bpo91, mixed mode, sharing)
The problem sounds similar to https://github.com/Insubstantial/insubstantial/issues/56#issuecomment-333986024 where it is attributed to a bug in Substance, which I see is included in your jar.

Hi
I appreciate for developing this software firstly.
I have a problem importing data. I have received a message that was related to An unexpected error has occurred (java.lang.NullPointerException). The program will be terminated". Please let me know how I can solve it.
Thanks

Hello,
Is there way, we can other formats besides web of science into citenetexplorer software?
1. How to use SCOPUS data file into software.
2. Guidelines to use Pakej file is also not very clear
Can you please address these issues?

Hi,
I'm starting to work with it and Web of Science data, but it only works with one file. I have around 730 publications, so I downloaded 2.txt files. When I upload them into the CitNetExplorer I got this error: "An unexpected error has occurred (java.lang.NullPointerException). The program will be terminated" and then it closes.
Thanks!

Hi
As the previous message I have the same problem to import a merge file of five export files from WoS. How could I resolve the problem.
Thank in advance
Fernando.

Hi,
Thank you for this software, it is very useful!
I'm starting to work with it and Web of Science data, but it only works with one file. I have around 2300 publications, so I downloaded 5 .txt files. When I upload them into the CitNetExplorer I got this error: "An unexpected error has occurred (java.lang.NullPointerException). The program will be terminated" and then it closes.
I really appreciate your help.
Thanks!

Hi!
Thank you for an excellent piece of software.
Will it be possible in the future to upload one paper to the software, then view the 'family tree' of citations that it uses, for each generation?
For example, if Paper A cites Papers B, C & D, the family tree would display connections from: A to B, C & D
then connections from B to all of its cited papers x,y,z
and connections from C to all of its cited papers i,u,j
etc.
Thank you kindly.

Hi,
I know I can convert Scopus files via CRExplorer and then bring them onto CitNetExplorer to use. But when I just go to CRExplorer and put my excel file, it says that there is an error in the analysis. My other excel files get this but not the one I need to use immediately for the project. Is there something about excel I am missing out on? I am saving the file as a CSV. Thank you.

Is there any way to get the most relevant research paper from the network??

Hello, I'm trying to make a citation network for about 1700 files from one publication. I've downloaded them in 500-article batches from Web of Science and saved them as .txt files. I try to upload the first .txt file to CitNetExplorer but get an error that says my "file is not valid." What am I doing wrong? Thanks!

Hi,
I'm trying to visually differentiate between publications based on their language of publication. Is there a feature to do this in CitNetExplorer that someone could direct me to? Otherwise I've been attempting to look at my data set in excel and manually select each publication that I know to be in a certain language, which is rather inefficient. Thanks in advance!

Hello! One more question: where can I find examples of "citation network patterns"? And, if is it possible, in specific reference to qualitative fields of investigation (e.g. citations patterns referring to the network made by all publication on a topic such as "social farming")
many thanks in advance
Matteo

Hallo Ludo nice to meet you!
I tried to save a scopus data files as WOS by using crexplorer but I did not succeed.
How to do it?
kind regards!
Matteo

Hello,
I would like to create a publication map for an initial technique paper and show its subsequent citations. I think CitNetExplorer should be able to show this over time. If so, do I import the one publication of interest from WOS with a full record and cited references? I have tried this but only see the one publication and none of its citing papers. Also, what type of network map would be the most appropriate to create in VOSViewer to show the citation impact of one key publication? Thank you!
Lesley

Hello! I need to use a thesaurus file in my CitNet analysis since I have some duplication of the same authors, is it possible like in VosViewer? Thank you in advance

Many thanks for the great work!!! Quick question: is it possible to visualize more than 40 documents at once in the network?
thanks in advance!

thx

I can't get the software to work... I get an error with the following text "Error while reading Web of Science files (my path). Cannot find author (AU) field. I checked with random files (not with the whole bunch at ones) - didn't help. Thank you in advance!

I am having trouble analyzing a large number of citations. The software churns for a while, and eventually gives an error: "Out of memory, the program will be terminated". However, my system has plenty of spare memory available, but CitNetExplorer only consumes 1.1 GB before running into issues. This is on a Win64 system.

Hello Dear All
Can you help me with assistance to overcome an error that appears whenever I try to use "screenshot" to "save a map" in any of the available formats (.pdf, .png,..)?
It says "An unexpected error occurred (java.lang.UnsatisfiedLinkError: sun.awt.X11GraphicsEnvironment.initDisplay(Z)V). The program will be terminated."
It is very frustating because I loss all the adjustments that allow the perfect map to include in the paper. I am using VOSviewer as well and it works perfectly. So, what could be my problem with CitNet?
Can you help, please? Thanks.

Dear Dr. Waltman,
I have been using both of your software for some time and they are fascinating. However, it seems that I get different result in clustering in the two software. I found that "Use external Citation Score" seems not functioning for me. When I choose external citation score, the citation score for all articles goes to Zero. I am using the software from University (Radboud). Do have any suggestion for that?

is there a way to export Data from google scholar and import it into CitnetExplorer as well?

Hello,
I'm trying to use the CitNetExplorer view instead of the Web of Science view when importing citations. I'm attempting to import the citations as a .txt file in the "Citations File" field, but I'm not sure what the "Publications" file is. What are the parameters for the "Publications File"? Is this something I have to download?
Thanks!

Dear CNE,
Thank you very much to launch CitNetExplorer. I have one question for you: I do not have access to Web of Science, but I have access to SCOPUS. Would you tell me how to import bibliography from SCOPUS to CitNetExplorer. May I import .RIS file?
Thank you very much.

Hi,
If I have a list of PDFs of journal articles. How can I conduct a co citation analysis using CitNEtExplorer?

* Are networks constructed by CitNetExplorer based on DOI?
If a publication that does not have a DOI, does it appear in network visualisation?
* Does CitNetExplorer work well with 64 bit Windows system? What is the minimum requirement for RAM? I tried to visualize a network of more or less 100,000 publications in Windows 10, but failed. The error is either "Out of memory" or "File is empty". Could you help? Thank you!

Dear CitNetExplorer team,
First of all, I hope that everyone is fine and many thanks for your appreciated efforts.
I am trying to use CitNetExplorer, however, every time I try to upload text file of the citations by following your instructions I got an error that said: Error while reading web of science file 'path': File is empty. Could you please help me with such issue? Thank you in advance.
Best wishes,
Alderasus

Hello,
Great free tool. One question, which is the minimum number of references needed for running the clustering option? I am trying with different options but it appears that due to minimum size requirement they can't be clustered. Do you have any additional tutorial or recommendation for managing other options that are not explaining in this tutorial (e.g. I am trying to find the option for connecting the lines between nodes, but I just don't find it!-as Ian below-).
Many thanks,
Paola

Hello!
Does this support the data extract from Scopus database. Is there any way to use the Scopus data for citation analysis.
Thanks
Best regards
Gaurav

Great program, the connecting lines between nodes seem to have disappeared on my visualization. I can't work out how to bring them back. Any advice much appreciated.
Thanks

Some references could be very old and do not right include (Annonymus). Could we introduce changes in the publication list to rename the reference?

Hello! I enjoy the idea of the software presented here, but when I attempt to save my records of interest from Web of Science, I am unable to download reference information. The dropdown menu for Record Content is only "Author, Title, Source" and "Author, Title, Source, Abstract", and the "Full Record and Cited References" option has been evidently removed.
What can I do to still use CitNetExplorer?
Thanks for any insights!
Alex

I imported a bunch of records from Web of Science which have definite citation relations among them.
But no citation links are showing up
Why is that?

Does anyone casually have any macro for exporting scientometric / bibliometric entities from VantagePoint software to CitNetExplorer so that citation trees can be created?
I do have one macro for exporting from VantagePoint to VOSViewer which I obtained from VantagePoint Institute webpage (MakeVOSfromatrix.vpm).
Otherwise I will have to program one myself by VBA scripting :-)
Thank you :-D
