Re: [Freesurfer] Very different results between 5.1.0 and 5.2.0
Looking at the image posted previously. https://yalesurvey.qualtrics.com/SE/?SID=SV_ddwW7I9yMQuCtPn I think it is pretty clear the 5.1 picture has better gray/white contrast. It is a very subtle difference, but you can see it if you look at some pieces of wm that were missed by 5.2 in this image.

Re: [Freesurfer] Very different results between 5.1.0 and 5.2.0
The 5.2 image has been smoothed, by a small degree, relative to 5.1. Either prior to FS processing or by FS, it would seem.

Re: [Freesurfer] nu_correct: Command not found error
I have encountered this error in the past, and I think it was because I was not sourcing SetUpFreeSurfer.sh correctly.

Re: [Freesurfer] parcellations to fmri space
I tried using mri_label2vol with --aparc+aseg instead of --aparc. This works and provides cortical and subcortical with no overlap. It doesn't allow me to do cortical dilation, but that is probably because it wouldn't mesh well with the subcortical ROIs. Thanks.

[Freesurfer] bbregister
I have run a bunch of cases through bbregister and overall it worked great! 315 out of about 325 cases the alignments were very good, but on 10 subjects it did very poorly. I can not so far find anything unusual about this data. Per earlier posts, I have tried the different initilization options with no luck. I also tried an fsl_rigid_register 6 DOF to create a starting .dat ,but that was way off too, maybe because it uses similar initilization information? I also saw the post to use --init-reg-out to save the init transform but I am not sure what to make of the output. This is aligning data that has been through the 1000FC pre-processing. This converts our RAS scans to RPI, and also de-obliques using AFNI. Would you suspect either of these steps as confusing bbregister?

Re: [Freesurfer] DODS and DOSS
Michael, Thanks for your response. It was helpful. As you suggested the thickness-age correlation group difference under DOSS is meaningless, so I have ignored that output. I am currently left with a situation where under the DOSS model I see a large ageXthickness effect (controlling for group) and a nearly identical map under the DODS model. So far so good. When I look at the group difference map, I see a large group difference for the DOSS model, and a LOT less for the DODS model. This would lead me to believe that the extra DOF in the DODS model is removing the group difference because my two groups have different ageXthickness slopes and when this is properly accounted for in the DODS model the group difference largely goes away. However, when I look at the does the thicknessXage correlation differ between groups map I see almost nothing significant? I guess my hypothesis is that the slopes are different enough between my groups to wash away the group difference, but not large enough to show up as significant? It would be nice to be able to derive some per group ageXthickness slopes from clusters or ROIS to investigate this further, is this possible? I will probably also start looking into other models, just visually looking at different vertices it appears that most of the groups difference is in the older subjects (in terms of raw thickness values) with less/none difference in younger subjects. One last aside. The demeaning of covariates still slightly confuses me. In a DOSS model it seems it wouldn't matter where you measure the intercept since both ageXthickness slopes are equal. In the DODS model, it doesn't seem to make sense to measure an intercept of two different slopes, it is more interesting to compare the slopes (in the case of different slopes you will get a different answer at every possible intercept). I am obviously a newbie to GLM and QDEC so sorry for any silly questions. Chris On Fri, Mar 4, 2011 at 1:34 PM, Michael Harms mha...@conte.wustl.eduwrote: Hi Chris, There really shouldn't be a thickness-age correlation group difference result with the DOSS model. I have FS 4.1 (rather than 5.0 on my system) but running an analogous model, I see that I do indeed get a verbal Description for such a contrast. However, if I compare that to the thickness-age correlation (accounting for group) result, I see the exact same map. And if you look at the .mat files in the contrast directory generated by qdec, you'll see that those two contrasts are identical (i.e. [0 0 1]) (or at least they are for qdec with FS 4.1). So, this appears to be a bug in the verbal descriptions that qdec provides when using a DOSS model. As to the group difference itself changing between the DOSS and DODS models, that is totally to be expected. Note that in the DODS model, whether or not you demean (center) the age variable has a critical impact on the manner in which you interpret the group contrast. cheers, -MH On Thu, 2011-03-03 at 20:41 -0600, Christopher Bell wrote: FreeSurfers, I have been analyzing my qdec data in version 5.0 and have some interesting although somewhat confusing results.

When I look at the results for DODS I get: thickness-age correlation (accounting for group)---result: much of brain significant group difference (I assume controlling for age, but it doesn't say explicitly)--result: one small roi significant thickness-age correlation group difference--result: one small roi spatially adjacent to group difference roi When I run DOSS I get: thickness-age correlation (accounting for group)---result: much of brain significant group difference (I assume controlling for age, but it doesn't say explicitly)--result: much of brain significant thickness-age correlation group difference--result: much of brain significant I am mostly surprised by how much larger the (group difference), and the (thickness-age correlation group difference) increase with the DOSS method. I am also not quite how to interpret the thickness-age correlation group difference in DOSS. I was thinking the DOSS method constrained both groups to have the same slope and so I was expecting to get nothing for difference in thickness-age correlation difference by group; isn't this suggesting my two groups have significantly different ageXthickness slopes even though they are constrained to have the same slope by the DOSS method? It would almost make more sense to me if the results were reversed between DOSS and DODS. If I had a large thicknessXage correlation group difference using the DODS method which allows for different slopes. Thanks for any enlightenment.
