Hi, Thank you for the advice. I have a follow-up question. I seem to be getting a warning: non-equal flip_angle found for the volume 1. Flip_angle is set to zero. The full log is at the bottom. Using freesurfer-Linux-centos4_x86_64-stable-v5.1.0-20110514 Setting up environment fo

why do you want parameter maps? What acquisitions do you have? On Fri, 5 May 2006, adam walczak wrote: Ok. Thanks. So what would the data I use to make the parameter maps also work for the reconstruction pipeline? Adam Bruce Fischl <[EMAIL PROTECTED]> wrote: you don't need it at all if you

At what point in the processing pipeline is mri_ms_fitparms? I am trying to convert data without header information (TE, TR, Flip angle) to data that freesurfer can use using mri_ms_fitparms and entering that info.  This creates a T1 and PD image but I want to run it through the entire reconstruct

yes to the T1. The PD units are arbitrary and includes other things like T2*. On Fri, 2 Dec 2005, Christian Haselgrove wrote: Hi, What exactly is contained in the outputs of mri_ms_fitparms? Specifically: the T1 volume looks like it might have T1 times in ms -- is this correct? And I ass

Hi, What exactly is contained in the outputs of mri_ms_fitparms? Specifically: the T1 volume looks like it might have T1 times in ms -- is this correct? And I assume that PD is proton density -- is there a specific unit attached to these voxel values as well? Thanks, Christian -- Christia
