If you instal MCR (MATLAB Compiler Runtime) provided by GISTIC package, may have the following error. This error could disrupt GISTIC. libGL error: failed to load driver: swrast

If this situation occurs, rename the file found at " $MATLAB_ROOT/sys/os/glnxa64/libstdc++.so.6" to “libstdc++.so.6.old”, This forces MATLAB to use the OS library.

Works for me.
