Re: [Freesurfer] Estimate of number of manual edits and time to complete in 100subject sample
Hi Kev, For the two scenarios you mentioned, here are my best estimates. I assume a healthy, adult population scanned with our recommended sequences. Any other type of dataset (pediatric, one with some type of pathology, one acquired long ago using a less than optimal sequence or coil, etc.) would likely differ by a lot in terms of time estimates. 1. fMRI on good quality 3T Maybe 25 out of 100 need some kind of intervention, including restarting a process that may have failed along the way. I would expect these 25 to have something terribly wrong with them to make them unacceptable for fMRI analysis but something that is most likely easily fixed by an automatic intervention. I'd estimate a half hour for each of the 25 or an hour for each to be extremely conservative. 2. Cortical thickness on good quality 3T Maybe 50-75 out of 100 need some kind of intervention, depending on which areas you might focus on if you're not only interested in global thickness. Edits on half of those will be very small, 15-30 minutes a case. Edits on the other half may be more time consuming, 30 minutes to 1 hour. Allison On Tue, 5 Mar 2013, Schumman Resonance wrote: This is a question for the FS community in general, I gather there is variability around this, but rather than an exact number and time, I was hoping for an estimate on how many scans would I expect to require manual edits(any of the check points recommended in the tutorials) as well as an estimate of the time it takes to go through them. For the sake of the argument, take a sample of 100 subjects.

Re: [Freesurfer] Question regarding control points
Although the white surface finds its place based on intensity, it's starting point is the wm.mgz. So if there are no voxels in the wm.mgz in the area you mention, drawing in some voxels combined with the intensity changes that come from the control points may help.

But since it's a step clearly 'behind' correcting the skull strip and adding control points, and it takes a lot of work to accurately draw the WM mask, I would prefer to automate things as much as possible... @Alan, thanks for your suggestion - although 1 CP for 2 voxels appears to be a lot. Tomorrow I'll check whether adding CP's helps.

Re: [Freesurfer] Recommended reconstruction wiki
Hi Martijn, autorecon-cp is correct, we start the process a bit earlier now. But even better, regardless of what edits you make, you can rerun with recon-all -make all and it will start at the earliest needed step. (Although running from autorecon2 after the skullstrip fix is correct as well).

Re: [Freesurfer] white matter edits
Vincent, Some may look like holes but as you mention are just sulci being cut through by that plane. A way to check if it is the above is to put the cursor on the surface that creates this hole and then toggle to the other views (sagittal, axial, coronal). It will become clearer whether it is a sulcus or not in the other views based on where the cursor is located. It takes some getting used to in order to differentiate the errors that appear as holes vs. sulci if you are not used to looking at the anatomy this way. But the sulci will be in the same areas brain to brain and you will get used to ignoring them. You can also use tksurfer to help identify true errors (they will look like holes or bumps on the surface).

They seem to be ubiquitous throughout all 20 of the brains I have processed.
