Check the raw data for that run and see if the head didn't move out of the FOV.

Hi, I was just working with some of the HCP volume data and noticed that subject 101107 had a chunk of ventral prefrontal cortex missing in the rfMRI_REST1_LR.nii.gz volume (in MNINonLinear/Results/rfMRI_REST1_LR). Interestingly, the brain mask for rfMRI_REST1_RL.nii.gz seems different (more inclusive). I thought that the brain masking was based on the anatomicals (T1w and T2w), and was therefore the same across functional scans? Either I misunderstood the brain masking procedure, or there is an issue in the minimally preprocessed data for 101107. Screenshot of REST1_LR and REST1_RL volumes, side by side, attached.
