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! Xiaomin
