Thank you, I was not aware of the #frame extension!

a couple of different ways would work. The frams are numbered starting at 0 for the first one. So for frame #5 (the 6th one) it would be:

mri_convert -nth 5 file.nii file.frame5.nii

Alternatively, all of our tools accept the extension #<frame #> so you could do:

mri_convert file.nii#5 file.frame5.nii

Hello again,

I have a large time series in dicom or .nii format. I am interested in extracting a single time frame from it. I did this before, I believe with freesurfer, but I have somehow forgot the name of the command, and I can't seem to find it. I believe it could be used to specify particular regions of the volume, as well as time. I need the entire volume, still, but only one frame.

Thanks in advance!

Eli

I'm not sure what this refers to because there is no history in the email. I'm guessing that you want to extract a certain range of frames from a multiframe file. If so try the  --fsubsample  option in mri_convert

Hello,

Specifying a single volume frame with # is great, but how to specify a range or multiple arbitrary choosen frames? Something like #0..9 would be nice for the 1st to the 10th frame, and #0,2,4 for the 1st, 3rd and 5th frames.

Thanks for the help and Have a very good day! Sebastien
