Hi Expert,

In the latest version of FS, I have segmented the thalamic successfully. But I can't use Freeview to show the segmentation map. There is an error :"freeview: /usr/lib/libpng15.so.15:version 'PNG15_0' not found (required by /opt/freesurfer/bin/../lib/qt/lib/libQt5Gui.so.5)". May be I didn't install the latest version of Freeview. However, I can't find this version on Freesurferwiki.  Could you share me the install steps and the latest version? Thanks very much for your help.

Sincerely,

Zheng
