-------- Forwarded Message -------- Subject: Postdoc position available - computational modeling of fMRI/MEG data, and real-time fMRI neurofeedback of language Date: Wed, 10 Jun 2020 10:54:03 +0000 From: Narly Golestani <Narly.Golestani(a)unige.ch> To: Narly Golestani <Narly.Golestani(a)unige.ch> External Email - Use Caution Dear Colleagues, I would be grateful if you could please circulate the below job advertisement to anyone who may be interested. Many thanks in advance and best wishes, Narly. ****************************************** With the launch of a new ‘NCCR Evolving Language’ (http://www.snf.ch/SiteCollectionDocuments/nfs/Faktenblatt_NCCR_evolvinglang…) which involves nearly 40 different research groups from a large variety of disciplines across Switzerland, we seek to fill a *Postdoc position for a four-year project* starting in September 2020, or at the selected candidate’s earliest convenience. Our goal is to make progress in understanding *the importance of prosody in language processing*. To this end, we plan to carry out a set of studies involving both *computational modeling of fMRI *and/or of*MEG data *and*real-time fMRI neurofeedback *to understand the *mechanisms whereby prosody and rhythm support linguistic processing per se*. The computational modeling work will be an extension of our recent work on the neural encoding of acoustic information in speech sounds (https://www.ncbi.nlm.nih.gov/pubmed/31285622) The research will be done in the group of Narly *Golestani*in Geneva (www.brainandlanguagelab.org <http://www.brainandlanguagelab.org>), in collaboration with researchers in Switzerland and abroad (Elia *Formisano*in Maastricht, and Frank *Scharnowski*in Vienna). Applicants should hold a degree in *Cognitive Neuroscience*, *Biomedical Engineering, Computational Neuroscience, or a related field*, and should have solid experience in *human brain imaging *and*programming*, and ideally also *in computational modelling (i.e. encoding / decoding) of fMRI *and/or of*MEG data, real-time fMRI based neurofeedback, machine learning and statistics*. Knowledge of French would be an asset. The NCCR places great emphasis on gender diversity and we particularly encourage women to apply. To apply, please send a cover letter, CV, names and contact information of 2-3 references as well as any other relevant documents to Narly.Golestani(a)unige.ch <mailto:Narly.Golestani@unige.ch>. Feel free to contact me should you have any questions. *Deadline for application: June 30^th 2020.* *-----------------------------------------------------------------------------------------------------------------------------------------------------------------* *Brain and Language Lab* **Prof. Narly GOLESTANI* * Department of Psychology Campus Biotech *9 Chemin des Mines, * *1202 Genève* *+41 22 379 53 52* <https://outlook.unige.ch/owa/redir.aspx?SURL=5WTo-p-J-W9FrDydU-0WU4PdMytUGs…>http://www.brainandlanguagelab.org https://twitter.com/brain_lang_lab *-----------------------------------------------------------------------------------------------------------------------------------------------------------------* <https://outlook.unige.ch/owa/redir.aspx?SURL=5WTo-p-J-W9FrDydU-0WU4PdMytUGs…>

Unmatched error
by COLLEEN PLETCHER 09 Jun '20

09 Jun '20

External Email - Use Caution Hello, I am currently attempting to run a brain through the longitudinal stream after performing edits on the longitudinal brain, using the command recon-all -long timepoint1 base -autorecon2-wm -autorecon3. I am getting an error that says Unmatched ". All of the data for both timepoint 1 and the base is there and readable. I am using version 6.0. Any advice on how to fix this problem? Thank you!

Re: [Freesurfer] recon-all -long erros

As for the --preserve=timestamps error, this is a bug on osx. This will be fixed in the next 7.1 patch, but in the meantime, you can fix this manually via: cd $FREESURFER_HOME/bin sudo rm rca-long-tp-init sudo curl https://raw.githubusercontent.com/freesurfer/freesurfer/dev/scripts/rca-lon… -o rca-long-tp-init sudo chmod +x rca-long-tp-init best Andrew On 6/9/20, 7:36 AM, "Martin Reuter" <mreuter(a)nmr.mgh.harvard.edu> wrote: Hi Jieyin, a couple things I noticed: 1) you call this: recon-all -long P0567/tp4 P0567/tpm -all this is not the way recon-all should be called. You need to specify a SUBJECTS_DIR under which all your time points exists usually you would have $SUBJECTS_DIR/me_tp1 $SUBJECTS_DIR/me_tp2 $SUBJECTS_DIR/me_tpm # (the base or subject-template) $SUBJECTS_DIR/me_tp1.long.me_tpm # (output of long stream) $SUBJECTS_DIR/me_tp2.long.me_tpm # (output of long stream) $SUBJECTS_DIR/you_tp1 $SUBJECTS_DIR/you_tp2 ... If you want a separate directory for each subject, you would need to specify that dir in SUBJECTS_DIR and then the names would just be tp1 tp2 tpm tp1.long.tpm etc. It could be that the / in the subject name messes things up! 2. The command that fails is: /Users/jif19007/Documents/PLING_dataset/MRI_raw/pilot_data/output_P0567 /tp4.long.tpm/mri cp -f --preserve=timestamps /Users/jif19007/Documents/PLING_dataset/MRI_raw/pilot_data/output_P0567 /tpm/mri/brainmask.mgz ./brainmask_tpm.mgz cp: illegal option -- - maybe the mac has problems with the --preserve flag? I don't know when this was added and whether it is really necessary. Currently I don't even know where this is called. Can't find it in recon-all. Maybe some sub-script?

lGI permutation and monte-carlo
by Avi Gharehgazlou 09 Jun '20

09 Jun '20

External Email - Use Caution Hi experts, Upon reading your 2018 paper (cited below) and following threads on the archives, I am aware that I should use permutation testing for lGI analyses rather than monte carlo at p<0.05. However, I have a few questions below that I would really appreciate your input on: 1. For permutation testing on lGI data, what are the CFT and cwp levels you recommend? Would it be appropriate for me to use CFT=1.3 and cwp=0.05? 2. Will you confirm my interpretation for permutation command line below? mri_glmfit-sim --glmdir lh.lgi.TD_PTSD_age_SA_IQ_FWHM0.glmdir --perm 1000 2 abs --perm-resid --cwp 0.05 --2spaces --bg 1 Above command indicates that I used a cluster-forming threshold of p<0.01 and a cluster-wise significance threshold of p<0.05 - meaning that clusters are initially obtained using p<0.01 (CFT) but I report them in my paper if they meet additional cluster-wise probability of p<0.05 (cwp). Both are two-tailed (since I am using abs). Is this interpretation correct? 3. Would it be okay to correct with monte carlo using CFT=3 and cwp= 0.05 (below command line) instead of permutation testing for lGI data? mri_glmfit-sim --glmdir lh.ASDvsADHD.glmdir --cache 3 abs --cwp 0.05 --2spaces 3. I am not smoothing my lGI data (as lGI is a relatively smooth measure and to keep this consistent with the literature I have reviewed), however, after reading your 2018 paper, I wanted to ask if this is appropriate? Your paper recommends CFT<0.001 and FWHM>10mm for surface area analyses. Do I have to smooth lGI when doing a) permutation testing or b) monte carlo correction (steps 1 and 3 above)? If yes, what level of smoothness do you recommend? 4. After correcting with monte-carlo at p<0.05 - When I use the below command line to see my corrected results in freeview, I notice the significant cluster is gray rather than blue (I know it should be blue because I've ran this same analysis using QDEC). In order to see this cluster's true colour (and thus be able to interpret my results) do I have to change the threshold by clicking ‘show outline overlay’ then clicking ‘configure’ and setting the min value to 1.3? Is this the correct way of visualizing my corrected results? vglrun freeview -f $SUBJECTS_DIR/fsaverage/surf/lh.pial:overlay=lh.lgi.TD_PTSD_age_SA_IQ_FWHM0.glmdir/group.diff/cache.th13.abs.sig.cluster.mgh:overlay_threshold=1.3,5:annot=lh.lgi.TD_PTSD_age_SA_IQ_FWHM0.glmdir/group.diff/cache.th13.abs.sig.ocn.annot -viewport 3d reference Greve DN & Fischl B. 2018.

Permutation --perm-resid unrecognized
by Avi Gharehgazlou 09 Jun '20

External Email - Use Caution Hi experts, I am trying to run permutation test on my lGI data using the command line below but I get an error saying “ERROR: Flag --perm-resid unrecognized”. I've ran my mri_glmfit command line with flag --eres-save (see below) and have installed and made executable the new version of mri_glmfit-sim as instructed here: ( https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/MultipleComparisonsV6.… ) Will you please tell me how I can fix this? permutation command line I used: mri_glmfit-sim --glmdir lh.lgi.TD_PTSD_age_SA_IQ_FWHM0.glmdir --perm 1000 4.0 abs --perm-resid --cwp 0.05 --2spaces --bg 1 mri_glmfit command line I used: mri_glmfit --y lh.lgi.TD_PTSD_age_SA_IQ_FWHM0.mgh --fsgd fsgd.txt dods --glmdir lh.lgi.TD_PTSD_age_SA_IQ_FWHM0.glmdir --surf fsaverage lh --C group.diff.mtx --C group-x-age.mtx --C group-x-SA.mtx --C group-x-IQ.mtx --C lgi.intercept.mtx --C maineffect.age.mtx --C maineffect.IQ.mtx --cortex --eres-save Also, is it okay to run the --eres-save flag with mri_glmfit regardless even if I decide to do another correction (i.e. monte carlo later later on) or would results get affected? Thank you so much for your support, Avi
