Detrend and filter

Submitted by ma.shalchy on Sat, 10/25/2014 - 20:06

Dear all
Hi

Sorry for these basic questions.
I would like to detrend and filter my rfmri images. However, I could not find an specific option for this on rest tool kit. IS it ok to use the detrend and filter feature of ALFF or fALFF or...?

Secondly, as I run rest toolbox there is a pop up window as "Set Rest Workers; Parallel Computation Toolbox detected.How many workers do you want rest to use?"
What is this and what should I set it as?
Many thanks in advance.

Best,
mahsa

Re: Detrend and filter

Hi,

For Q1, you can use the detrend and filter feature of ALFF, fALFF, ReHo, Fun.Connectivity and so on.
For Q2, this option is used to run with the parallel computations. if your computer has multiple processors, you can speed up your processor by setting the number of workers.

Best,
Taro
