The problem seems to be due to the large susceptibility distortions at 7T. I chose two subjects at random (100610 and 126426) and the issue is there in both so it is potentially systematic. Note: I downloaded the pre-processed volume data and in there I found the data of interest in MNINonLinear/Results. I assumed that this is the correct data which has gone through the pre-processing pipeline and has been corrected for distortions. I’m aware that the 7T retinotopy tasks have not yet been described in the S1200 documentation and that the data may not be final yet. Any advice would be appreciated. Many thanks, Ahmad -- Ahmad Beyh, MSc NatBrainLab King’s College London ahmad.b...@kcl.ac.uk<mailto:ahmad.b...@kcl.ac.uk> _______________________________________________ HCP-Users mailing list HCP-Users@humanconnectome.org<mailto:HCP-Users@humanconnectome.org> http://lists.humanconnectome.org/mailman/listinfo/hcp-users _______________________________________________ HCP-Users mailing list HCP-Users@humanconnectome.org http://lists.humanconnectome.org/mailman/listinfo/hcp-users
