Hello Bruce, Our Psychology program allows a double major in Clinical Science and Cognitive Neuroscience. Please have her contact me if she is interested. There are excellent faculty in both programs and it is highly collaborative across the two programs, so lots of opportunity for training in

Re: [Freesurfer] T2pial and [LONG]

2016-10-29 Thread Martin Reuter
Hi Antonin, almost, you need to use the existing transforms from the base (when the T1 template get’s created) and apply these to the co-registered T2 of each time point. In recon-all base code you will find a mi_robust_template call that takes existing lta transforms for each time points an

Re: [Freesurfer] Two Stage Longitudinal Model

2016-10-29 Thread Martin Reuter
Hi Tim, yes, in the 2-stage approach, you first compute the slope per subject (e.g. mm/year thinning or q mm per year volume loss) and then do a regular GLM for each subject. For that the co-variates need to be fixed per subject. The long_qdec_table command below averages the covers for you. Yo

Re: [Freesurfer] Question regarding Checking Longitudinal Runs: Repost

2016-10-29 Thread Martin Reuter
Hi Tamara, if you have time and only few subjects, I would recommend to look at all those. For a large study it becomes difficult. Just open the base and both time points on top to see if they all align and if the base looks OK. We also usually recommend to check the surface in base, but if y

Hi Tamara, 1. brainmask.mgz 2. yes, as you will get your final measures from the long output stats. Take a look at how aseg edits are done in the regular cross stream. In long it would work the same (just with passing -long and then instead of -all you just do the last steps to recompute the s

Hi Tom, Could be the qdec table has weird characters. Try with a simplified table (only a few rows, created in a text editor from scratch, space separated). best, Martin > On Oct 12, 2016, at 11:59 PM, tom parker wrote: > > Dear FreeSurfers, > > I've been trying to run a longitudinal cort

Quinn, Could be that the table has any strange character in it (e.g. strange white space etc. ) Try to create a table in a simple text editor by typing the header line and the first 1 or two rows (space separated). If it can read that, then it is probably the format of your table. Best, Mar
