Re: [Freesurfer] mprage flag in recon-all

[Harms, Michael]

Sorry, I misinterpreted your question.  In that case, if you want more than the broad-brush description that Bruce provided, you'll likely need to download the source code and scour the c-code yourself to find the exact specifics. cheers, -MH --  Michael Harms, Ph.D. ----------------------------------------------------------- Conte Center for the Neuroscience of Mental Disorders Washington University School of Medicine Department of Psychiatry, Box 8134 660 South Euclid Ave. Tel: 314-747-6173 St. Louis, MO  63110 Email: mha...@wustl.edu From: "Caspar M.

I would like to know what -mprage does in these two functions, but i cannot search them because they are executables, not scripts. Caspar 2013/5/31 Harms, Michael <mha...@wustl.edu> Use any editor (even Word) with a search capacity, and search for the string 'mprage'. That will lead to you the variable internal to recon-all called "IsMPRAGE".  Searching for "IsMPRAGE" will then show you all in the stages that the -mprage flag affects. cheers, -MH --  Michael Harms, Ph.D. ----------------------------------------------------------- Conte Center for the Neuroscience of Mental Disorders Washington University School of Medicine Department of Psychiatry, Box 8134 660 South Euclid Ave. Tel: 314-747-6173 St. Louis, MO  63110 Email: mha...@wustl.edu From: "Caspar M.

You'll need to look in the recon-all script for the details cheers Bruce On Thu, 30 May 2013, Caspar M. Schwiedrzik wrote: Hi! Is there more documentation on what settings the mprage flag enables in recon-all? Specifically, I would be interested which individual steps it affects and what  the parameters are for each of the steps. Thanks!
