Equivalent of fslswapdim for left-right flipping fsLR 32k surface data?
Hi everyone, For my volumetric analysis, I compared LH and RH movement by left-right flipping the RH runs after fMRIPrep preprocessing (registered to MNI152NLin2009cSym) using fslswapdim. I did this to analyze my data in an ipsilateral/contralateral framework, where the left hemisphere was always ipsilateral to the moving hand and the right hemisphere was always contralateral. I’m now trying to do the same thing with fMRIPrep-generated fsLR 32k surface data files, but I’m not sure what the equivalent approach is. Is there a recommended way to left-right flip RH fsLR data?

Asking for advice: Incomplete Field of view messed up FA-V1 (primary eigenvector alignement) on diffusion tensor imaging data?
Hello, I am currently doing preprocessing on some diffusion tensor imaging subjects. I have multiple subjects with a bad field of view unfortunately (They have the top of their cortex cut off). When I applied FSL dtifit (tensor fitting) on these subjects, I noticed that the alignement of V1 (longest eigenvector) with the fractional anisotropy (FA) was often badly misaligned to the point I could not use them for TBSS. These subjects don’t have opposite phase encoding and range from 7 volumes (1 b0, 6 gradients) to 32 volumes (1 b0, 32 gradients). To analyze the alignement, I used the enigma FA-
Do you know reaserchers in neurochemistry theoretical?
Hello to everyone! i’m chemist, my thesis of undergraduate was in theoretical chemistry about proton transfers in basis of DNA , i would like make a phD about this area with focus in neuroscience specially in Alzheimer or any other neurodisease or mental disorder. So, i would like know if this is possible or if you know any researcher that work in this? I really thankful if you help me! 1 post - 1 participant Read full topic
Clarifications on what BIDS schema says about denoting new lines in tsvs
The BIDS schema has an error code relating to new lines # BIDS Validator Original Issue Code #70 WrongNewLine: code: WRONG_NEW_LINE message: | All TSV files must use Line Feed '\n' characters to denote new lines. This files uses Carriage Return '\r'. level: error selectors: - extension == ".tsv" I’m not sure how to interpret this. Does “This file uses Carriage Return“ imply that validators should check for the presence of carriage returns (that is, separating lines with CRLF is disallowed), or does it mean that validators are checking for the use of carriage returns alone
Need advice/guidance on using RSA on fMRI data
I am using an fMRI dataset from openneuro.org, it has 2 tasks, which are on task switching and language switching, and each task has four trial types, each task has 2 runs and each run has eighty trials. so I am beginner and teaching myself on fMRI preprocessing and fMRI analysis(using nilearn), want to do a publication worthy hands on project. My methodology is - Sub - 001 - extract voxel time series for specific ROI of task 1 do the same for run 2 and concatenate both runs resulting in 160 x number of voxels construct 160 x 160 RDM for this ROI construct model RDM of 160 x 160 calculate S
Postdoctoral Research Scholar at Stanford University
Description: We are seeking a postdoctoral scholar to join the laboratory of Dr. Supekar and contribute to two NIH R01-funded projects at the intersection of neuroscience, artificial intelligence, and precision psychiatry. The Supekar lab integrates neuroscience and artificial intelligence (AI) to advance understanding of brain function and the mechanisms underlying neuropsychiatric disorders. Through rigorous research and clinically oriented translation, we develop evidence-based innovations to improve diagnosis, prognosis, and treatment, with the ultimate goal of improving outcomes for indiv
