Tutorials on how to use Gephi
Gephi provides some excellent tutorials, avialalbe both as videos and in PDFs. I prefer the latter since you can more quickly find the material you are interested in. See the Gephi users page (contains links to videos and PDFs).
Troubles Running Gephi
Installing:
Get error message "Cannot find Java 1.8" or similar. Gephi has issue with not finding where JAVA is installed.
1) you should install JAVA (1.8 is current). https://www.java.com/ES/download/
2) you must edit gephi.conf file to point it to JAVA location https://github.com/gephi/gephi/issues/1880
Dr. H: for Windows.
a) locate JAVA directory folder. (shows during installation). Generally something like
C:\Program Files (x86)\Java\jre1.8.0_241
b) go to Gephi installation folder, generally something like
C:\Program Files\Gephi-0.9.2
c) go to "etc" subfolder, where you should find gephi.conf file
d) use editor to modify file
CHANGE
# default location of JDK/JRE, can be overridden by using --
jdkhome <dir> switch
#jdkhome="/path/to/jdk"
to
# default location of JDK/JRE, can be overridden by using --
#jdkhome <dir> switch
#jdkhome="/path/to/jdk"
jdkhome="C:\Program Files (x86)\Java\jre1.8.0_241"
the lines started with "#" are comment lines. So the last one is the active working line in the new version.
it points Gephi to where JAVA is on your system.
Replace "C:\Program Files (x86)\Java\jre1.8.0_241" with whatever location is on your computer.
Resetting View: I kept getting lost/confused with my visualization; i.e. nothing would appear, or the controls around the border would disappear, or the layout/filter setting would be all off. Solution: on the upper tabs click Window THEN Window Reset.
