Dear all,

I am totally new to PESTICA & SLOMOCO. I have two questions:

1. Should I run PESTICA first and then SLOMOCO, or SLOMOCO first and then PESTICA?

2. I have a 4D dataset file, named f.nii. After I set up PESTICA, I tried to execute run_pestica.sh. But it immediately showed an error message. Can you please advise how I can resolve this and move on?

Thanks!!
Daniel

run_pestica.sh -d f -s

* Creating PESTICA Directory: f_pestica

***** f.brain+orig.HEAD does not exist, creating mask
note, if you wish to use your own mask/brain file, kill this script
then 3dcopy your mask/brain to f.brain and re-run.
PESTICA will use whatever resides in f.brain

running 3dSkullStrip -input f+orig -prefix f.brain

done with skull-stripping - please check file and if not satisfied, I recommend running
3dSkullStrip with different parameters to attempt to get a satisfactory brain mask.
Either way, this script looks in f_pestica/ for f.brain to use as your brain mask/strip
