Version 5.3 vs. Version 6
by Larissa Bechtle 08 Nov '19

08 Nov '19

External Email - Use Caution Hey everybody, i have a question concerning version 5.3 and 6.0 of freesurfer. Originally I used 5.3 for volumes and thickness as well as for a group analysis. Later I used 6.0 for an anatomical ROI Analysis. I read online that doing so should be okay but wanted i wanted to make sure that this is really the case. I am thankful for any answer! Best wishes Larissa

Re: [Freesurfer] LME model contrast matrix (Diers, Kersten /DZNE)
by Liu Guodong 07 Nov '19

07 Nov '19

External Email - Use Caution Hi Kersten, Thank you so much for the reply and that helps a lot. There are still some questions that I hope you can help me. 1.For the first model in you last email, you said 'To get the mean for group B, one would need to add the beta weights of the two regressors.’. I wonder if the beta weights should be 1 for regressors1 and 1 for regressor2, and the mean for group B is regressor2 plus regressor1 with the condition the value of group B is bigger than group A. 2.Is there any P-value for the lme_fit_FS function to present the quality of the fitting? 3.As you said before, if I have 3 group A,B,C for this model, and group A is reference group, the regressor1 is the mean of group A, and regressor2 and 3 reflect the difference between group A and B,C. But if I want to know the difference between B and C, what should I do. From the F-test, there only have a P-value to reflect how different between group B and C, I wonder can I compute a value the same as regressor 2 to reflect the difference? Thanks!

Re: [Freesurfer] nuisance factors
by Georgina Angelopoulou 06 Nov '19

06 Nov '19

External Email - Use Caution Apologies for sending again, I would like to verify that you have received the email. Thank you in advance for you help, Georgina I am sorry, please let me rephrase. I want to compare patients vs controls in Surface area and grey matter volume. I have already checked age slope and it is not significant for either GMV or SA. However eTIV slope is significant in both cases (we do check for eTiv slope first as we did for age, right?) So in that case that we have two nuisance variables (age and eTiv), eTIV is significant but age isn't, how are we going to formulate the contrast? Would 1 -1 0 0 0 0 be correct? Thanks once again, Georgina

External Email - Use Caution Dear Kersten: The β1 and β2 in the tutorial model is the regressing coefficients for all the subjects not only for the control subjects because all the intercept are one. I wonder why the reference group is control group in this case? Thanks in advance.

Question re: Longitudinal processing stream transforms.
by Jamie Hanson 05 Nov '19

05 Nov '19

External Email - Use Caution Dear FS List, My group was trying to look at the overlap between cortical labels in the longitudinal processing stream and I had a question re: use of transform files. In brief, we followed the commands for the longitudinal processing stream, creating a "subject-specific" template for each participant ( https://surfer.nmr.mgh.harvard.edu/fswiki/LongitudinalProcessing#WorkflowSu…, using FS v.6.0). We processed T1w images multiple times and now, we wanted to transform the time 1 and time 2 (native space) scans to their subject-specific template. We used the following commands-- mri_vol2vol --mov $INDIVIDUAL_SCAN_TIME1_DIR/sub-BNU_25864_001.long.sub-BNU_25864_template/mri/brain.mgz --o $INDIVIDUAL_SCAN_TIME1/brain_001_to_temp.mgz --lta $SUBJECT_SPECIFIC_TEMPLATE_DIR/mri/transforms/sub-BNU_25864_001_to_sub-BNU_25864_template.lta --targ $SUBJECT_SPECIFIC_TEMPLATE_DIR/mri/brain.mgz But when we did this for time 1 and time 2 scans, they were poorly aligned. I also used the lta file for template to 001, but again things were poorly aligned. Should we be using m3z files? Or combining different transforms? Any guidance or suggestions are deeply appreciated. Thanks much, Jamie. -- Jamie Hanson Assistant Professor, Psychology Research Scientist, Learning Research and Development Center University of Pittsburgh Personal website: jamiehanson.org

Using individual FreeSurfer utilities without the whole package
by Mike Schmidt 04 Nov '19

04 Nov '19

External Email - Use Caution Cursory googling has not turned up a solution to this, but I expect it may have been asked before. I would like to use several FreeSurfer utilities (mri_convert, mri_binarize, mri_pretess, mri_tesselate, mris_convert) in a docker container to post-process existing FreeSurfer output files. Creating a full FreeSurfer docker container is easily done. But ideally, I'd like to keep the container as small as possible so I would like to avoid using the whole 6GB package. While the license seems to legally allow derivative works like this, I'm not sure how the individual executables check for the license file, what the dependencies are, how tangled the web of dependencies may be, etc. 1. Is this a supported use and/or solved problem that I just haven't found in my searching? 2. If not, does anyone have a reason to warn me away from wasting time going down this road? Thanks for the benefit of others' experience, Mike Schmidt
