RE: Analysis step error, minimal denoising

[color=#000000]Hi Scott,[/color]

[color=#000000]Could you please check in the first-level analysis definitions that you are entering in the 'sources' list only valid ROIs? (if you enter as sources, for example, things like the 'scrubbing' covariate that may result in similar issues). If that seems to be ok please send me the files ROI_Subject001_Condition001.mat and ROI_Subject002_Condition001.mat from the conn_*/results/preprocessing/ folder to see if that helps me figure out the issue here.[/color]

[i]Originally posted by Scott Burwell:[/i][quote]Hello, 

I have preprocessed my data in SPM12 (slice-time correction, coregistration, segmentaion, normalization) and would like to perform ICA in CONN with minimal preprocessing and denoising. I have setup my preprocessing and denoising below (please see [b]Exhibit A[/b]).  I get an error message when it goes to ROI-to-voxel first-level analyses (please see [b]Exhibit B[/b]). The code runs without issue when I have more nuisance variables (e.g., "White Matter", "Grey Matter") entered as preprocessing confounds. Additionally, if I run the GUI after the denoising step, it appears that all subjects/seeds possess the necessary ROI data, and it seems like the denoising preview is valid. I am using an explicit mask (brainmask.nii from SPM)

Any thoughts?

Thank you in advance.
Scott
