Hi Doug

I was wondering if you could find a time to look at the data I shared with you in filedrop?

I appreciate if you could please let me know whenever you had time.

Thanks

Mona

That is strange as it should get masked out. Can you upload the fmri session to our file drop?

Dear Freesurfers

Hi

I have a bunch of data which have field of view mis-displacement at the time of data aquisition, so when I overlay the functional data on the structural image, the top part of the brain is cut off.

Below I have copied one of the subject's functional image overlaid on his structural image on the right and the result of first level analysis (single subject map) in two different thresholds on the left. I have also copied one of the registration slices on the bottom.

My question is why there is activation on parts of the brain which doesn't really have a functional data?

Should I preprocess these data in a different way than the usual way?

Thanks a lot

Mona
