trac-preproc error
by Hasimoglu, Yasemin 05 Nov '20

05 Nov '20

Hi, I'm running Tracula on a longitudinal dataset and it's failing at the preproc stage for one subject with the following message: INFO: Distances between consecutive points in test subject's space are 16 13 12 14 WARN: Could not find satisfactory control point fit - try 4967 Finding center streamline INFO: Step is 3 voxels WARN: Turning off deviation check for center streamline INFO: Step is 3 voxels WARN: Turning off FA check for center streamline INFO: Step is 3 voxels WARN: Turning off overlap check for center streamline INFO: Step is 3 voxels WARN: All checks already off. Exiting. Selecting 5 points on center streamline ERROR: Selected streamline has fewer than 5 points Linux zorii.nmr.mgh.harvard.edu 3.10.0-1062.4.3.el7.x86_64 #1 SMP Wed Nov 13 23:58:53 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux trac-preproc exited with ERRORS at Wed Oct 28 04:11:51 EDT 2020 It looks like the problem is with one specific pathway. I checked the brainmask and the inter and intra-subject registrations and they all look fine to me, so I'm not sure what else to check. The trac-all.log file is quite large, I attempted to attach it in this email several times, but it always gets rejected, so I'm not attaching it for now. I would greatly appreciate any advice! Best, Yasemin

LGI quality control {Disarmed}
by Nelson, Eric 05 Nov '20

05 Nov '20

External Email - Use Caution Hello, I am using FreeSurfer 7.1.1 to run LGI and have done so successfully. I am now trying to quality check my data using tksurfer as described on the wiki tksurfer my_subject_id lh inflated -overlay lh.pial_lgi However the LGI overlay is not covering the entirety of the inflated brain. Specifically the medial frontal surface and some subcortical are not measured for LGI. Here is a link of the overlay images for a few subjects: https://secure-web.cisco.com/1FvGKanOWU0exqsmfZZWyCdCgTFgqf8kB2BXdsF-5A035k…. I<https://secure-web.cisco.com/1yytrZan4Ml7C4NJTkc91uplhrETEPm4MAwDFEYaEAXtVl…>. I haven't been able to find any images of what this overlay should look like so I don't know if this is expected or if something has gone wrong with the processing. Any feedback would be greatly appreciated Best, Eric

Question about smoothing for extracting anatomical stats {Disarmed}
by Hye Min Shin 05 Nov '20

05 Nov '20

External Email - Use Caution Hello experts, So I understand that when doing mri_glmfit you want to use smoothed surface maps to comply with random field theory while controlling for multiple comparisons (as discussed here: https://secure-web.cisco.com/1pNAU-NVIkRxQvX9B5btXENpnudT80URPA00UsXPU064w3…) But I was also wondering whether we have to smooth surface maps when using mri_anatomical_stats to extract anatomical measurements? I see that mri_anatomical_stats has the option to smooth by # of iterations but is there a way to know how many # of iterations would equal let's say 15 FWHM? Best, Julia Shin

External Email - Use Caution The Basque Center on Cognition, Brain and Language (BCBL) is holding a free online next week. We hope that it can be of interest to this community, and that you could forward others this information. At the BCBL, we are organizing the third edition of Brainhack Donostia (https://secure-web.cisco.com/1GC1hh4vsRCGfthBadagfSojiEis8P2rIcxlvHWMBmSe1m…) an event focused on neuroscience and the promotion of open-source resources in an accessible way across disciplines and experience levels. This year's edition is taking place from November 9 through November 13: it will be held online and will be completely free. The focus of BHD2020 will be OpenScience, covered from a variety of pertinent perspectives (e.g., MEG, fMRI and fNIRS). We are going to have the cream of the crop as invited speakers, check the schedule here: https://secure-web.cisco.com/1nN_lXzurOj1ntsI3lbjeAWTurwndamZGsnyiXQE9Xqhw7…. Even though we will be physically distant, there will be the possibility to come together and socialize on the Brainhack Donostia GatherTown platform. We will be using the platform to host exciting social activities throughout the event. Stay tuned for the social activities program! We invite all neuroscience aficionados, students of neuroscience-related subjects, professors and professionals to participate. Registrations are now open at https://secure-web.cisco.com/1d3VTvJ1ukmPmrYp15NgAyjM96L0VJDHuND2s9vyXzTZc5….
