It has something to do with the fact that we needed to apply manual reclassification of the FIX output in that particular subject/run.

For subject 204218, both REST1_LR and REST1_RL, I noticed a linear trend in the *_hp2000_clean.nii.gz NIFTI time series, but the hp2000_clean.dtseries.nii CIFTI files do not have this trend. See attached figures showing this issue for both REST1_LR and REST1_RL for 204218. The overall mean time series has a negative trend for NIFTI, but in the voxel time series on the left you can see that some have positive trend and some have negative. To test, I did run fslmaths-based filtering on hp2000_clean.nii.gz and I no longer see any linear trend. I tried one scan in one additional subject, 102311 REST1_LR, and did not see this linear trend in either NIFTI or CIFTI (also attached). Note: I did remove the overall mean for each voxel timecourse before plotting, and for the NIFTI I'm only showing gray matter voxels, as determined by downsampling aparc+aseg.nii.gz and excluding labels for WM,CSF,ventricles, and a few misc. I also tried looking at all non-zero voxels, as well as only those marked in RibbonVolumeToSurfaceMapping/goodvoxels.nii.gz, but the issue of linear trends is the same. Any idea what might be going on with this subject? I haven't tried this in anyone other than 204218 (bad) and 102311 (good). -Keith _______________________________________________ HCP-Users mailing list HCP-Users@humanconnectome.org http://lists.humanconnectome.org/mailman/listinfo/hcp-users ________________________________ The materials in this message are private and may contain Protected Healthcare Information or other information of a sensitive nature.
