Hello Colleagues,
I recently installed AFNI_21.0.12 on Ubuntu 20.04 (built Feb 23 or 24, 2021) and noticed that 3dROIstats was very slow. Taking 2.5 minutes for 3.5x3.5x4 data with 300 TRs. I creating a whole brain mean time course using a whole-brain mask (e.g. 1 inside the brain 0 outside). I verified this same behavior on Ubuntu 16.04. I get the same slow performance with and without PIGZ enabled using environment variables.
I built the latest code from the AFNI github repo using Makefile.linux_ubuntu_16_64 on Ubuntu 20.04 and get the same slow behavior.
AFNI_20.0.04:Linux_ubuntu_64 built Jan 29, 2020 does the same extraction takes 1 second on Ubuntu 16.04 and 20.04.
Any thoughts on how to fix this? In the mean time, is there a place where we can download an earlier build? We will be building a new container for CPAC soon and would like to avoid this problem.
Cheers,
cameron
