Sorry for the delay, I was hoping to get some input from another on why my numbers seemed off. I have attached a screenshot which I believe has an image of an example which needs to be fixed, along with the coordinates. Please let me know if you need anything else,

I don't know what coordinates those are. Can you give indices? indices are non-neg

what is the index (ie, col, row, slice) where you are seeing a problem?

Hi,
I am not sure if this email got lost in the process or is still awaiting approval, but I was asked to tar and gzip the images that I was having no luck with fixing the white matter for. Any help would be appreciated. Thank you,

I have still been having trouble with fixing the white matter of the aparc+aseg.mgz file for a subject. I have tried using
recon-all -autorecon2-cp -autorecon3 -subjid XXXX recon-all -autorecon2-wm -subjid XXXX recon-all -autorecon2-wm -autorecon3 -subjid XXXX
None of these have solved the issue, and I was hoping for help in finding a way to fix this? There are other more extreme examples, but this one seems to have an error at [-7, 114, 133] Thank you for the help,

Hi Nicholas
why don't you tar, gzip and upload your subject and we will take a look. Make sure to tell us the coordinates of where you are trying to fix things

sections that should be white matter as such. Using the control points paired withrecon-all -autorecon2-cp -autorecon3 -subjid XXXX
did not work, after 4 or 5 attempts with different control points, and using recon-all -autorecon2-wm -s XXXX also did not yield appreciable results. Is there anything else that I might be able to try to fix this? Thank you for all the help,

In such situations, I have learned that autorecon2-wm after adding WM voxels seems to work pretty well. Hope that helps.
Best Wishes, Elijah

Bruce, Thank you for the response. Attempting to use this method has not produced results, and I am unsure how to proceed or if I had performed it improperly. I have attached an example of the control points being placed, if that helps any. Thank you,

yes, possibly, depending on why you are missing chunks. If the white matter in the regions you are missing has intensity values significantly < 110 then what you are doing should help. The control.dat file must be place in the subject/tmp dir for us to find it. cheers Bruce On Wed, 27 Sep 2017, Nicholas Goh wrote: I am attempting to fix the aparc+aseg.mgz file for an image, and wanted to check to see if I am doing it correctly.What I was doing which seemed to be ineffective was 1)create a new point set of control points labelled control.dat 2)place control points along what should be white matter 3)save point set 4)run recon-all -autorecon2-cp -autorecon3 -subjid XXXX Is this the correct way to go about fixing aparc+aseg files that are missing chunks of the brain? Is there a better way to go about this?
