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
Brad
