External Email - Use Caution        

Hi Doug,

 

I used FS 7.1 under WSL to analyze retinotopy data.  Since the ring and wedge were presented at a different frequency, the data had to be analyzed separately for each condition.  To get the field sign, I had to use the mri_fieldsign function to combine polar and eccen data.   However, an error happened with running mri_fieldsign: “Segmentation fault      (core dumped)”.  The following is the command-line output.

 

Thanks for your help!
