I am trying to run mris_anatomical_stats -f <file name> for seeing the results get written into a file, but it says "unknown option" for -f.

Clustering methods for multiple comparisons
by Glenn Lawyer 18 Jan '06

18 Jan '06

Hi, Doug, You mentioned on the list that you are preparing a tool that uses clustering to reduce the multiple comparison penalty. Do you have time to post some more details, or perhaps just pass along some of your references? This area is very interesting to me. +glenn -- I want to go farther, farther! A. E.

Simple ? about T1.mgz
by Clifford A. Smith, PhD 12 Jan '06

12 Jan '06

I¹ve been going over the tutorials, but my question remains is T1 skull stripped? It seems to check skull stripping brain.mgz is loaded as the main volume with T1.mgz as the aux. Flipping back and forth (control 1/control 2) is used to check the stripped brain.mgz. This implies T1 has the skull still (yet my T1 images are all skull stripped). Thanks.

mri_watershed
by dwakeman＠nmr.mgh.harvard.edu 11 Jan '06

11 Jan '06

Hi, I am having a problem with mri_watershed. The data is @ /space/linus/12/users/dwakeman/subjects/P1B2au1/ I called recon-all -subjid P1B2au1 -autorecon1 The error message is at the bottom. running mri_watershed -atlas T1.mgz brain did not work. There is no brain.mgz file generated, so I cannot look to see what the problem is. I have one other problem on a side note, I am generating a true step by step tutorial, which will serve to both teach people about freesurfer and teach them how to use it. I am using the Recommended ReconTable as a basis for this tutorial. In the table, it says that autorecon1 does 4 iterations of nu_correct; however, when the nu_correct command is run individually it says that it performs 2 iterations. I would like to know if this means that a total of 8 iterations are run in autorecon1 or if the equivalent to autorecon1 is two iterations of the nu_correct command. Thank you for your help on both problems. Dan *************************WATERSHED************************** preflooding height equal to 25 percent Sorting...
