Dear community,
I have some BOLD data on which I’d like to run connectivity analysis. I preprocessed te data using fMRIprep, and now I’d like to use xcpengine for nuisance regression.
I have decided to use the fc-acmopcor.dsn pipeline. Following Murphy et al. (2020) “Multimodal network dynamics underpinning working memory”, I would like to add Global Signal Regression on top of the aCompCor pipeline.
The way I chose to do so is to edit the fa-acmopcor.dsn file, replacing:
“confound2_gsr[2]=0”
with
“confound2_gsr[2]=1”
The reason I am worried is that looking at the “confound2” output directory, I see that a file names “sub-011_task_rest_run-1_gsr.1D” was not created.
I would appreciate comments on this approach. Is this the correct approach? Would that regress the global signal in an apropriate manner?
Any advice would be greatly appreciated.
Best,
Roey
