M-SDB

[mkim]

Hello.
I have a question as to what M-SDB stands for. My c-pac output directories get named in the following way: _selector_CSF-2mmE-M_aC-CSF+WM-2mm-DPC5_M-SDB_P-2_BP-B0.01-T0.1

I can make out which regressors each of the abbreviations stand for except for M-SDB (in bold). I am guessing it is related to motion and the Friston 24-Parameter Model (see pipeline config below), but I cannot figure out what SDB stands for. I am also hoping for confirmation that it means that motion-related artifacts were regressed out during the preprocessing and that I would not need to regress them out during the subsequent analysis step.
 
My regressors from the pipeline config file are listed below:
- Bandpass:
bottom_frequency: 0.01
top_frequency: 0.1
CerebrospinalFluid:
erode_mask: true
extraction_resolution: 2
summary: Mean
Motion:
include_delayed: true
include_delayed_squared: true
include_squared: true
PolyOrt:
degree: 2
aCompCor:
extraction_resolution: 2
summary:
components: 5
method: DetrendPC
tissues:
- WhiteMatter
- CerebrospinalFluid

Thank you.

Hello,

M-SDB means all 3 (delayed, squared, and delayed+squared).

A quick note: C-PAC v1.8+ allows you to name your own nuisance regression strategies.

Best,
