Error: Nu Correct

Hi all, I am trying to use FreeSurfer to overlay FSL data. On running the command $ recon-all -stage1 -subjid TEST I get the following error, Nu Intensity Correction Tue Mar 1 14:54:08 EST 2005 mri_convert orig nu/nu0.mnc mri_convert orig nu/nu0.mnc reading from orig... TR=1.00, TE=0.00, TI=0.00, flip angle=0.00 i_ras = (-1, 0, 0) j_ras = (0, 0, -1) k_ras = (0, 1, 0) writing to nu/nu0.mnc... nu_correct -clobber nu/nu0.mnc nu/nu1.mnc nu_correct: Command not found. ERROR: nu_correct I do have MNI Tools installed, in the freesurfer folder. Please let me know what I should do. Thank you. Harshad.

Hi, I have a question regarding convertion of raw multi-echo data to bfloat format. I used the following command in seychelles: pbsubmit -c "run-recon-monkey /space/stego/5/users/wim/edgar050218 1 6 7 8 > edgar050218_1.out" -p -m reza@nmr.... The converstion has been done succesfully for one functional run but then it has been stoped and there is the following error message: ??? Error using ==> reshape To RESHAPE the number of elements must not change. Error in ==> /homes/4/greve/anders/mdh_io/read_mdh_adc_VA21.m On line 114 ==> adc_data = reshape(adc_data, 2, mdh.SamplesInScan); Error in ==> /homes/4/greve/anders/mdh_io/read_mdh_adc.m On line 5 ==> [adc_data, mdh] = read_mdh_adc_VA21(fid); Error in ==> /homes/4/greve/anders/mdh_io/read_mdh_and_mrprot.m On line 151 ==> [adc_data, mdh] = read_mdh_adc(fid,VersionNum); Error in ==> /homes/4/greve/anders/recon_Monkey_fMRI.m On line 199 ==> [kdat1,krev1,ktim1,pcdat1,pcrev1,pctim1,h1] = .. . I do not know what this error message refers to. I would be thankful if anyone has a suggestion. Best Wishes, Reza -- ******************************** Reza Rajimehr, M.D. NMR Athinoula A.

Tksurfer Error
by Harshad Shanbhag 24 Feb '05

24 Feb '05

Hello, I am facing a problem in running tkmedit or tksurfer. So I looked up the posts and found a thread which explained using tkmedit.static instead of tkmedit. I did that and I could run tkmedit. However, I can't find the tksurfer.static file in that same directory. Please let me know how I could run tksurfer. I get this error message when i run tksurfer from the command line. tksurfer: error while loading shared libraries: libglut.so.3: cannot open shared object file: No such file or directory. Thank You. Sincerely, Harshad.

Error running recon from command line
by Harshad Shanbhag 23 Feb '05

23 Feb '05

Hello, I installed FreeSurfer according to instructions on the website. To overlay FSL data, I used the following instructions from the FMRIB website. avwswapdim TEST x -z y TEST_reorient slices TEST_reorient bet TEST_reorient TEST_brain -f 0.4 mri_convert /home/bbernal/freesurfer/subjects/TEST/mri/orig/001/TEST_brain.img . recon-all -stage1 -subjid TEST However, the program gives me errors at this stage. I saved the error messages to the file that I have attached. Could you please have a look at it and help me with this. Thank you. Sincerely, Harshad.

Cortical thickness correlated with age
by Claus Tempelmann 23 Feb '05

23 Feb '05

Hi everybody, for quite a while we have been comparing the cortical thickness between groups of patients and I hope we did everything as we should. Now, we have been trying to look for the correlation between cortical thickness and age and somewhere we seem to make a mistake. I know that it's difficult for you to find this mistake as there are many possible sources. Nevertheless, I hope that somebody has an idea ;-) Let me describe what we did: 1. We have a group of subjects, for all of the subjects we went through the steps of segementation, inflating, sphering, morphing ... 2. We edited a simple mtx-file named PatBas-Alter1.mtx (this is not the complete group, we just started with a few subjects to check the method). This file has only two columns, column 1 is the name of the subject in the SUBJECTS_DIR, column 2 is the age of the subject: Patient_2_Baseline 33 Patient_4_Baseline 42 Patient_5_Baseline 27 Patient_6_Baseline 40 Patient_7_Baseline 35 Patient_9_Baseline 48 Patient_10_Baseline 31 Patient_12_Baseline 29 Patient_13_Baseline 33 Patient_14_Baseline 37 Patient_15_Baseline 36 Patient_16_Baseline 41 Patient_17_Baseline 41 Patient_18_Baseline 26 Patient_21_Baseline 30 Patient_22_Baseline 37 3. We run mris_glm with a script or directly from the command line: (we are using version 1.18, 2003/06/30 20:40:38 greve) mris_glm --design $mtxfile.mtx --surfmeas thickness --hemi lh --trgsubj average7 --nsmooth 50 --gcv 0 0 1 --sigt sigt_$outputname-lh.w paint 4. We render sigt_$outputname-lh.w on the inflated surface of average 7. The result is surprising. Everywhere in the brain the cortical thickness shows a high positive correlation (t-values between 9 and 12) with age. Obviuosly, that's nonsense but I haven't seen any error message. 5. To check what may have happened we edited the mtx-file according to the motto the last will be the first, high age is assigned to young subjects and viceversa. 6. The resulting t-maps look very similar. They are not identical but again the cortical thickness shows a high correlation with (now faked) age, again we get t-values between 9 and 12. Any ideas what might have happened? I'm sure that we made something very stupid but what can that be?? Our mtx-file has only two columns. Can that be a problem??

new tkmedit and tksurfer
by Wan Park 17 Feb '05

I am supposed to have libtiff, glut, tclkt, tix and blt installed, but I still receive this message: for volume: Command Finished /usr/local/freesurfer_package/freesurfer/bin/Darwin/tkmedit 22970 T1 -csurf dyld: /usr/local/freesurfer_package/freesurfer/bin/Darwin/tkmedit can't open library: /sw/lib/libtix8.1.8.4.dylib (No such file or directory, errno = 2) Command Finished for surface: Command Finished /usr/local/freesurfer_package/freesurfer/bin/Darwin/tkmedit 22970 T1 -csurf dyld: /usr/local/freesurfer_package/freesurfer/bin/Darwin/tkmedit can't open library: /sw/lib/libtix8.1.8.4.dylib (No such file or directory, errno = 2) Command Finished Curiously, I did not have this problems before the new binaries. Do you think that may be a line or it is more about env? thanks! wan

surface atlas
by Nguyen, Thang Q 16 Feb '05

16 Feb '05

Hello all, I have a question: What atlas freesurfer uses when it parcellates the final surface? If I were using a different atlas for my functional volumes, can I warp the data to the proper atlas? Thank you, Thang Nguyen
