Hello Bruce, Thanks for the quick reply. I tried to follow your suggestions, there still seems to be some errors. Hence I am sending you the subject directory, at:
http://www.ensc.sfu.ca/~mfbeg/outgoing/topologyCorrectionProblem_PradeepFromSFU.tar.gz When trying to visualize the defect locations, this is what happened. I also tired running the mris_topo_fixer, but it was complaining that there is no lh.qshere.
