There is no direct way. But you can try this workaround:

Write all the screenshot command in a text file, line by line like this:

-v brain.nii -viewport sagittal -slice 80 127 127 -ss sag1 -noquit -viewport sagittal -slice 127 127 127 -ss sag2 -noquit …

Then run this command:

freeview -cmd cmd.txt

Dear FreeSurfer experts,

I understand that

...

freeview -v brain.nii.gz -ss screenshot

takes the screenshots and quits the freeview.

Regarding this, I have the following two questions.

(1) Is it possible to suppress the redundant GUI flashing?

It is really a pain when many images are batch-processed, because the GUI keeps flashing up and closing.

(2) Is it possible to take multiple screenshots with one session?

I wish to screenshot multiple slices of one image. I have tried

...

freeview -v brain.nii.gz\ -viewport sagittal -slice 80 127 127 -ss sag1 \ -viewport sagittal -slice 127 127 127 -ss sag2 \ -viewport sagittal -slice 156 127 127 -ss sag3 \

However, the session ends right after the first -ss, producing only one screenshot (sag1.png). I can surely do freeview -v brain.nii.gz 3 times to get these 3 screenshots, but that is very inefficient.

Thank you very much for your help in advance!
