External Email - Use Caution Hi freesurfer-experts, I am currently trying to run mris_prepoc. However FreeSurfer keeps telling me that there are no subjects specified. Thus, I think that the fsgd-file I created is the problem. I already checked it several times but still don’t know what’s wrong.

External Email - Use Caution Hi Dear experts, I downloaded and installed freesurfer on CentOS without any problem and also worked with it.

Re: [Freesurfer] Problem with freesurfer installation on mint 19 (ubuntu based OS)

External Email - Use Caution Hello Rashid, I would start with getting a cmake command to succeed to try and do the build.  Try looking over the cmake build page here,  https://surfer.nmr.mgh.harvard.edu/fswiki/CMake - where there is also makefile (makefile.wiki) you can download that should default to some useful settings for the cmake command on CentOS 6, 7, Ubuntu 16, 18, and MacOS   If you are on debian it will probably default to the CentOS 7 settings, but you could start from there. - R.

freeview showing results in a strange manner
by 姜时泽 22 Nov '18

22 Nov '18

External Email - Use Caution | | Dear freesurfer experts, I am using freesurfer to analyze my PET data according to the tutorial online. It works pretty well and I write the values of the results of each region to the template with Matlab (file attached here entitled "lh.subj1.mgz"). However, when I try to open it with freeview, the image looks quite strange ('Picture_1') but it works with tksurfer (Picture_2). Does any one know what is wrong with this? Did I plot the result in a wrong way? Thanks very much Shize -- Shize Jiang Fudan University, Department of neurosurgery, Huashan Hospital, Shanghai Medical College Shanghai,200032,P.R.China Mobile: (86)18317079839 E-Mail: sjiang13(a)fudan.edu.cn | | | |

Average subject normal data base
by m s 22 Nov '18

22 Nov '18

External Email - Use Caution Hi, I am looking forward to create a normal database for daily use to compare with individual patient mr volumes. I was thinking about creating an average subject from a normal database of multiple subjects. After I have my average subject, would it be posssible and correct to compare this average recon individually to a new subjects recon, redoing all the averaging and comparing process only between this two? Thank you Mercedes

'lh_G_Ins_lg&S_cent_ins_volume' and 'lh_G_insular_short_volume'
by Christophe Destrieux 22 Nov '18

22 Nov '18

External Email - Use Caution Hi Rujing Sorry for the late answer. These 2 labels correspond to the insula The insula is divided by the central sulcus of the insula (S_cent_ins_) into long insular gyri (G_Ins_lg) and short insular gyri (G_insular_short). Since the cortex lining the central sulcus of the insula was quite small, it has been grouped together with the the long insular gyri ( 'lh_G_Ins_lg&S_cent_ins_volume’) If you are interested in the volume of the whole insula you need to add the volumes of these two anatomical classes. For a complete list of anatomical classes and explanations on their anatomical meaning see : https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2937159/ Best Christophe Destrieux, Unité iBrain UMRS INSERM U1253, Université de Tours https://ibrain.univ-tours.fr/ <https://ibrain.univ-tours.fr/> Service de Neurochirurgie et Laboratoire d'Anatomie - Faculté de Médecine - 10 Bd Tonnellé - 37032 Tours - France tel (33) 2 47 36 61 36 - fax (33) 2 47 36 62 07 > Le 21 nov. 2018 à 17:12, Bruce Fischl <fischl(a)nmr.mgh.harvard.edu> a écrit : > > you are getting very popular! > > > ---------- Forwarded message ---------- > Date: Wed, 21 Nov 2018 14:30:13 +0800 > From: charujing123 <charujing123(a)163.com> > Reply-To: Freesurfer support list <freesurfer(a)nmr.mgh.harvard.edu> > To: "freesurfer(a)nmr.mgh.harvard.edu" <freesurfer(a)nmr.mgh.harvard.edu> > Subject: [Freesurfer] 'lh_G_Ins_lg&S_cent_ins_volume' and > 'lh_G_insular_short_volume' > > > External Email - Use Caution > > Hi, what is difference between and 'lh_G_insular_short_volume'.
