Dear Bruce,

Thanks for your reply.

I checked the folder and did not find the file that was requested.

What I have in the average folder that has 'RB*.gca' are 'RB_all_2016-05-10.vc700.gca' and 'RB_all_withskull_2016-05-10.vc700.gca'.

The other file in that folder is 'RB_all_2008-03-26.mni152.2mm.lta'.

Cheers,

Hweeling

Dear all,

I have T1 images collected from the 7T MRI scanner.

I downloaded the most recent freesurfer software, and followed all
instructions to install the software before using it.

I would like to segment the T1 data using its high resolution image, and
also to segment the hippocampal subfields.

For command, I use this:

recon-all -all -s <subject name> -hires -i <subject dicom T1 image frame 1
location>

However, I get an error message:

cannot find $FREESURFER_HOME/average/RB_all_2008-03-26.gca

I'm not sure what I did wrong.

Also, how can I combine high resolution segmentation and hippocampal
subfields segmentation?

Could someone please help?

Thanks.

Best regards,
Hweeling
