AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Hello,

Note that 3dAFNI2NIFTI is not very special, most AFNI programs can read and write either format, and therefore could be used for the conversion.

It is not clear how you are using idat, I don't think the program has such an option.

But programs will not generally separate a 4D dataset into subsets unless you tell them to. For that, it might be good to specify the volume indices of interest. For example (I will switch to 3dbucket, though 3dAFNI2NIFTI would work, too): 

3dbucket -prefix full_fstat.nii stats+tlrc'[0]'
3dbucket -prefix all_betas1.nii stats+tlrc'[1,4,7,10,13,16,29,22,25,28]'
3dbucket -prefix all_betas2.nii stats+tlrc'[1..28(3)]'
3dbucket -prefix all_tstats.nii stats+tlrc'[2..29(3)]'

Here, all_betas1.nii and all_betas2.nii would be the same dataset.

Does that seem like what you want?
