Installation problem
I'm sure I'm missing something obvious but I am having difficulty trying to get the BrainNet Viewer running. Environment is 64-Linux (Centos 7), MatLab 2018b. Downloaded the software and when running it, the following error is produced:

LD_LIBRARY_PATH is .:/usr/local/MATLAB/R2018b//runtime/glnxa64:/usr/local/MATLAB/R2018b//bin/glnxa64:/usr/local/MATLAB/R2018b//sys/os/glnxa64:/usr/local/MATLAB/R2018b//sys/opengl/lib/glnxa64
./BrainNet: error while loading shared libraries: libmwlaunchermain.so: cannot open shared object file: No such file or directory

I believe that since we have the full version of MATLAB installed, that the MATLAB Runtime is not needed. Regardless, I donwloaded it and it does not appear to contain the libmwlaunchermain.so file and neither does it exist in the /usr/local/MATLAB/R2018b directory.

What am I missing?

Any help would be greatly appreciated.

Hi Brad,

BNV is compiled in MATLAB 2018a. Could you please try install MCR 2018a? Here is the link: https://www.nitrc.org/frs/downloadlink.p...

Best,
Mingrui

RE: Installation problem
Mingrui,

Thank you for the reply but I had already tried that. I did though try again and the same error occurs. The issue is that there seems to be no library libmwlaunchermain.so in either a MATLAB installation or the MATLAB runtimes.

If possible could you look at your Linux installation of the BrainNet viewer and see if you and determine the location of this library and maybe that will point to the piece of the puzzle I am missing. Just in case you are not familiar with the Linux commands that would assist with this, either of the following are what I usually use:

locate libmwlaunchermain.so

or

find / -name 'libmwlaunchermain.so' -print 2>/dev/null

Thanks very much

RE: Installation problem
I was able to figure out what the problem was (don't ask ;-). Things are working as expected.

I know this is old...but I am having the same issue. What was the problem for you and how did you fix it? Thanks!
