Dear Freesurfer expert,

I am using Freesurfer version 5.1.0. 
I am dealing with some problems with recon_checker command.
I cannot open the html file to see the figures. The command generates the images but they are not saved. 
It is written that:
converting snapshots to tiff and making html page...
Convert: command not found

Any suggestions? 

Thanks in advance,
efrat
