External Email - Use Caution

Dear FreeSurfer experts

I have used this script to start Freeview from within Matlab

fs=getenv('FREESURFER_HOME'); setenv('FS_QT_HOME',fullfile(fs,'lib','qt')); setenv('QTLIBPATH',fullfile(fs,'lib','qt','lib')) setenv('qtplugin',fullfile(fs,'lib','qt','plugins')) setenv('vtk',fullfile(fs,'lib','vtk')) lib=getenv('LD_LIBRARY_PATH'); qtlib=getenv('QTLIBPATH'); plugins=getenv('qtplugin');

setenv('LD_LIBRARY_PATH',strcat(lib,':',qtlib,':',plugins,fullfile(fs,'lib','vtk')))

if upper < fdrtreshold upper = fdrtreshold + 1;

fdrtreshold=num2str(fdrtreshold);upper=num2str(upper); fdrtreshold=sprintf('%s,%s',fdrtreshold,upper);

leftcommand=sprintf('%s/%s/surf/lh.%s:annot=aparc.annot:annot_outline=1:overlay=%s:overlay_threshold=%s',SUBJECTS_DIR,template,surface,leftmgh,fdrtreshold); rightcommand=sprintf('%s/%s/surf/rh.%s:annot=aparc.annot:annot_outline=1:overlay=%s:overlay_threshold=%s ',SUBJECTS_DIR,template,surface,rightmgh,fdrtreshold);

freeview='freeview';

commandline=sprintf('%s -f %s -f %s -viewport 3d &',freeview,leftcommand,rightcommand);

system(commandline)

but with Freesurfer 7 I have been unable to start Freeview. Are there any option that I am missing. I get this error message

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: linuxfb, minimal, offscreen, vnc, xcb.

/usr/local/freesurfer/7.0.0-1/bin/freeview_matlab: line 13: 330961 Aborted (core dumped) freeview $argv:q /usr/local/freesurfer/7.0.0-1/bin/freeview_matlab: Aborted

Do I miss something that was setup by qt_setup?
