Custom LUT
by Benjamin Deck 31 May '22

31 May '22

External Email - Use Caution Hi freesurfer experts, I am attempting to create a custom LUT from a parcellation I created. I have projected the labels into the subject's volume space and then concatenated all of these volumtes together using: mri_concat --sum --f vols.txt --o sub_vols.mgz When I visualize these on the subject's t1w the number of ROIs looks approximately correct (n~105). However, my custom LUT seems to be incorrect. Not sure how that is. I used the FreesurferLUT as my template and added new colors and changed names of each row to match my file names (excluding the .mgz). Here is my custom LUT 0 Unknown 0 0 0 0 1 Net_10_ROIs_1_lh_native_sm6_sm6_dil2_lh_vol 5 5 5 5 2 Net_10_ROIs_1_rh_native_sm6_sm6_dil2_rh_vol 25 5 25 0 3 Net_11_ROIs_1_lh_native_sm6_sm6_dil2_lh_vol 25 100 40 0 4 Net_11_ROIs_1_rh_native_sm6_sm6_dil2_rh_vol 70 130 180 0 5 Net_12_ROIs_1_lh_native_sm6_sm6_dil2_lh_vol 100 100 0 0 6 Net_12_ROIs_1_rh_native_sm6_sm6_dil2_rh_vol 196 58 250 0 7 Net_12_ROIs_2_lh_native_sm6_sm6_dil2_lh_vol 100 25 0 0 8 Net_12_ROIs_2_rh_native_sm6_sm6_dil2_rh_vol 120 70 50 0 9 Net_13_ROIs_1_lh_native_sm6_sm6_dil2_lh_vol 220 20 10 0 10 Net_13_ROIs_1_rh_native_sm6_sm6_dil2_rh_vol 220 20 100 0 11 Net_13_ROIs_2_lh_native_sm6_sm6_dil2_lh_vol 180 40 120 0 12 Net_13_ROIs_2_rh_native_sm6_sm6_dil2_rh_vol 122 186 220 0 13 Net_13_ROIs_3_lh_native_sm6_sm6_dil2_lh_vol 140 20 140 0 14 Net_13_ROIs_3_rh_native_sm6_sm6_dil2_rh_vol 12 48 255 0 15 Net_13_ROIs_4_lh_native_sm6_sm6_dil2_lh_vol 20 30 140 0 ------and it goes on for 105 indices. here is my list of volumes Net_10_ROIs_1_lh_native_sm6_sm6_dil2_lh_vol.mgz Net_19_ROIs_1_rh_native_sm6_sm6_dil2_rh_vol.mgz Net_10_ROIs_1_rh_native_sm6_sm6_dil2_rh_vol.mgz Net_2_ROIs_1_lh_native_sm6_sm6_dil2_lh_vol.mgz Net_11_ROIs_1_lh_native_sm6_sm6_dil2_lh_vol.mgz Net_2_ROIs_1_rh_native_sm6_sm6_dil2_rh_vol.mgz Net_11_ROIs_1_rh_native_sm6_sm6_dil2_rh_vol.mgz Net_2_ROIs_2_lh_native_sm6_sm6_dil2_lh_vol.mgz Net_12_ROIs_1_lh_native_sm6_sm6_dil2_lh_vol.mgz Net_2_ROIs_2_rh_native_sm6_sm6_dil2_rh_vol.mgz Net_12_ROIs_1_rh_native_sm6_sm6_dil2_rh_vol.mgz Net_3_ROIs_1_lh_native_sm6_sm6_dil2_lh_vol.mgz Net_12_ROIs_2_lh_native_sm6_sm6_dil2_lh_vol.mgz Net_3_ROIs_1_rh_native_sm6_sm6_dil2_rh_vol.mgz -------and so on. Below I show that you can load each volume onto the brain and pick individual colors. [image: image.png] However, when I load the concatenated brain and load my custom image. All of ROIs get listed one of two ROIs. [image: image.png] Any guidance on this odd behavior would be much appreciated.

mri_normalize issues, Version 7
by Zoe O'Brien-Moran 31 May '22

31 May '22

External Email - Use Caution Hello FreeSurfer developers, I am attempting to run the mri_normalize function on T1 MPRAGE data and some of my subjects get an error: Iterating 2 times ------------- 3d normalization pass 1 of 2 error: No such file or directory error: MRInormFindControlPoints: could not find enough control points error: No such file or directory error: MRInormFindControlPoints failed This error comes up with some subjects but not others in the group with the same acquisition details. It is cross vendor (it has come up for both Siemens and Philips). Strangely enough, when I gave the data to someone else to run on their end, mri_normalize worked just fine... they are running FreeSurfer 5.3.0. On my own computer, running freesurfer version 7, I can get it to work by changing the orientation using mri_convert... though most subjects work with the original input orientation, and I would prefer not to have to do what feels like an arbitrary orientation change. Do you know why this could be happening? Were there any changes made to the mri_normalize function between v5.3.0 and v7? Thank you so much for any advice. Zoe O'Brien-Moran

External Email - Use Caution Hello FreeSurfer Developers, I am trying to run the mri_surf2surf command as shown in this MRtrix tutorial on page 35 (https://secure-web.cisco.com/1IRfOd9DbtoZ73ePUy1kNxDjehQaayodvb_Pq3LttY1M2Y…) in order to map the annotation files of the HCP MMP 1.0 atlas.
