Issues using curl for FreeSurfer tutorial data
by Karten, Jordan 09 Feb '21

09 Feb '21

Hi FreeSurfer Community, I was wondering if anyone else has been receiving the error "curl: (23) Failed writing body (8192 != 16384)" when attempting to download the data for tutorials, and if anyone had a solution that worked? I tried to find a fix online, but this issue seems to have many causes. Thanks for any help! All the best, Jordan

The Neurosmog project endeavours to investigate the effects of air pollution on behavioural and neural changes in school-age children. It combines four scientific teams in the fields of pollution assessment, child psychology, neuroimaging and epidemiology with the common goal of determining the impact of ambient air pollution on the developing brain in school age children. It uses MRI imaging and in-depth psychological testing of 300 cases of an ADHD group and 500 cases of a control group selected from the general population. Data collection has already began, and its end is foreseen in July 2022. This post is fully funded by a 3.5M EUR grant awarded by the Foundation for Polish Science (Fundacja na rzecz Nauki Polskiej, FNP) The candidate is expected to take the role the associate leader of a large-scale neuroimaging project with an enormous relevance to urgent public health issues. The position is initially for 33 months, and can be extended and converted into a tenure-track position on the condition of receiving external funding.

External Email - Use Caution Dear Freesurfer users, I hope this message is not out of place in this list. If it is, please ignore! I am writing to let you know about a high-level workshop we have organized titled "/The promises and Dark Sides of Artificial Intelligence in NMR, MRI and Neuroscience/", which is now online at https://secure-web.cisco.com/16ixw_i6BPFmKCirvs3yOpFZBsOe6rAcNXR8zplPC_9eTp… (complete info are available on the website). We are particularly glad to have recruited _eminent speakers both from the scientific field and from Industry_ (e.g. Philips, Siemens, Amazon Web Services etc.) and to have been able to include talks on e.g. regulatory and ethical aspects as well as sections on e_xplainability, clinical applications and precision medicine_. The format is both asynchronous (until *March 31st*) and synchronous (*live *session on Feb *19th, 2021*). ** The registration *deadline *is *Feb 14th. *The workshop also carries 30 ECM credits.* * In the hope that this initiative may be of interest for you, your group (Empirical Inference) and Institute (MPI for Intelligent Systems), I would be most grateful if you could relay this scientific and educational resource among your local community as well as professional networks. Please, do not hesitate to contact me for more information.

Number of threads in mri_em_register
by gunes 08 Feb '21

08 Feb '21

External Email - Use Caution Dear freesurfer developers, I'm using freesurfer v5.3.0 and having problems with the number of threads opened by `mri_em_register`. It automatically opens up as many threads as there are in the system, but I need to limit that. I have seen this post with the same problem: https://secure-web.cisco.com/19w3ZWmagO9QFaobk1ln0Z4sQQWaHjFCCO6n7ZqpGmL6VZ… In the end, it seems to be solved by setting OMP_NUM_THREADS to 1 in the mri_em_register script, but it is a binary file. I don't know how to set it. Kind regards, Gunes

Can't find longHippoSubfieldsT1.sh
by Xin Qi 08 Feb '21

08 Feb '21

External Email - Use Caution Dear Freesurfer Community, I ran the Freesurfer longitudinal pipeline for my subjects (1.5T, T1_data, 6 timepoints each). Now I want to continue with the longitudinal segmentation of hippocampal subfields:https://secure-web.cisco.com/1GVcN-oB6m3ReFE6G1f2L7PU8wxxvY2rraj4… However, when I want to run the command: longHippoSubfieldsT1.sh <baseID> I get the error message "bash: longHippoSubfieldsT1.sh: command not found" First thing I did, was checking the Freesurfer folder for the longHippo..sh file. I am using FS 7.0 but the file is not available. *So my questions: where can I get the file longHippoSubfieldsT1.sh or what else can I do to proceed with the HC subfield segmentation?* Thanks a lot for your support and looking forward to your reply. Best Xin

Recommendation for FreeSurfer BIDS derivatives?

External Email - Use Caution Hello In the BIDS-examples, we're trying to figure out whether we should use: 1) derivatives/freesurfer/sub-01/ses-01/ or 2) derivatives/freesurfer/sub-01_ses-01/ ? According to the FreeSurfer wiki, option #2 is recommended: https://secure-web.cisco.com/1sCCtE6LTMa-49XUNxEx--YIegNS1bF7eTcXR_u4FqKST7… But since the last time this page was edited was in 2018, we were wondering if this info is still up-to-date. Could someone comment directly on this pending PR? https://secure-web.cisco.com/1tQpQxw5ftUz9Yde9DKP1YMlGQWO1XQjNCa6L7RxMhdB2q… Thanks! Francois
