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

Hi experts,

I am using @auto_tlrc to convert my resting-state fMRI data to MNI152. After that, about 1/3 of the files get really huge. The input data is 610MB. The shape of nii file is [100 100 80 200]. The output data is 3.71GB, with shape [161 191 151 200]. The others (2/3 participants' files) are 138.3MB, with shape [54 64 50 200]. I wonder which one is correct. Dose files usually get larger after the convert or smaller?

Here's the code:
Quote
@auto_tlrc \
#-dxyz 3 \
-pad_base 50 \
-apar $i.T1.tc+tlrc \
-pad_input 50 \
-prefix $i.rs.tc \
-input $i.rs.aptopup_al+orig.BRIK

Thank you in advance!
