Dear Experts,

Could you please tell me where can I find the voxelwise time-series for each ROI subjectwise and conditionwise. I am using version 13i and during setup settings. I already checked from Setup>Options>Create Confound Corrected Time-series but could not find where it is saved.

Thanks a lot !!

Hi Sahil,

When you check the Setup>Options>Create Confoud corrected time-series option, the toolbox will create nifti files containing the BOLD times series for each voxel after removing of confounding effects, filtering, and concatenating across all of the repetitions for each condition. Those should be located in the folder

conn_*/results/preprocessing/

and named as niftiDATA_Subject###_Condition###.nii files (one file per subject/condition).

If what you want instead is to have the same timeseries but for each ROI (not for each voxel), then you can simply find these in the same folder but named as

ROI_Subject###_Condition###.mat files (one per subject/condition)

(and you do not need to have the Setup>Options>... option checked for these to be created, these are always created as long as you are performing ROI-to-ROI analyses). Within these files you will find a variable named 'data' containing the timeseries for each ROI, and a variable named 'names' containing the associated ROI names. 

Hope this helps
Alfonso

Hi Alfonso,

I would like to get the preprocessed time courses for each ROI from ROI_Subject###_Condition###.mat file.
Which variable can be used to build correlation matrix, data or d1data or d2data?

Thanks in advance
