Nima, There is no flag to mri_watershed to allow this, but you can trick it by doing the following: cd $FREESURFER_HOME/lib/bem mv ic5.tri ic5.bak ln -s ic4.tri ic5.tri This will force usage of ic4.tri, which has 5120 triangles. Nick On Wed, 2007-08-08 at 17:46 -0400, [EMAIL PROTECTED] w

Oh, don't do that! recon-all will compare the auto with the non-auto. If they are the same then it will re-compute the auto and simply copy to the non-auto, and your changes will be lost. If they are different, then it will recompute the auto but will not propagate it to the non-auto. Make sen

sounds like you saved it in COR format, which is what will happen if you specify a destination folder instead of a file name (e.g. brainmask.mgz). Try loading that in tkmedit to make sure it's got your edits, then you can convert it to .mgz with mri_convert. On Wed, 28 Jun 2006 [EMAIL PROTECTE

The brainmask.mgz file is the one that should be edited (and saved), so select that filename to save. Then just continue with autorecon2 (and it will use your brainmask.mgz). It will not overwrite your brainmask.mgz unless you specify the aptly named '-clean-bm' flag to recon-all. On Wed, 2006-

Alternatively, depending on what version of tkmedit you have, you can use the -mm-main option to specify an out-of-range min and max visible value on the command line. As Xiao said, normally the min and max visible values that determine the color scale are preset to the actual min and max v

Dear Sasha, mri_watershed was initially designed to skull strip orig images, without any preprocessing step, such as intensity normalization or contrast modification. So, This certainly seems like a reasonable thing to do. However, mri_watershed might normalize intensities during the process
