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

[enhance@nx2 Data]$
++ 3dTstat: AFNI version=AFNI_2009_12_31_1431 (Feb 25 2010) [64-bit]
++ Authored by: KR Hammett & RW Cox
++ Output dataset ./EPI_All_Runs_mean+orig.BRIK.gz+orig.BRIK

My first thought was that it was just a buggy progress message--that the filename actually being used was correct--but turns out it was telling the truth. I get

EPI_All_Runs_mean+orig.BRIK.gz+orig.HEAD
EPI_All_Runs_mean+orig.BRIK.gz+orig.BRIK

I tried to find out whether that file contained a gzipped dataset or not, but 3dcalc doesn't seem to parse -prefix under the same assumptions that 3dTstat does.

[enhance@nx2 Data]$ 3dinfo EPI_All_Runs_mean+orig.BRIK.gz+orig
++ 3dinfo: AFNI version=AFNI_2009_12_31_1431 (Feb 25 2010) [64-bit]
** FATAL ERROR: Can't open dataset EPI_All_Runs_mean+orig.BRIK.gz+orig
** Program compile date = Feb 25 2010

Why do different binaries have their own idiosyncrasies (i.e. different assumptions) about things like parsing dataset reference strings (whether input or output datasets)? For me at least, it's a regular source of headaches in scripting of processing using AFNI tools. If the code is modularized and the abstractions respected I don't understand the variations in behavior across the suite. sad smiley In addition to the particular issue above, if you could help me understand this better I'd appreciate it!

Thanks
