I’m new to fmriprep and recently attempted to use it for preprocessing my fMRI retinotopy dataset. Fortunately, I received the results without encountering any errors. Now, I’m interested in implementing analyzePRF on this preprocessed data. To achieve this, I need to obtain the time-series of the voxels from the preprocessed data. Therefore, I utilized the “mri_vol2surf” command from Freesurfer to extract the time-series. Subsequently, I tried loading the time-series in MATLAB using the “MRIread” function from Freesurfer/MATLAB. However, I noticed that the time-series for the voxels appeared to be unreasonable. Unfortunately, I haven’t been able to find any downloadable dataset that I can use to validate my approach. If any of you are aware of a dataset that can be used for validating the fmriprep docker image, I would greatly appreciate it if you could share the information. (I attempted to download the dataset used in the fmriprep docker image tutorial from “http://fcon_1000.projects.nitrc.org/indi/pro/eNKI_RS_TRT/FrontPage.html” and submitted a request to gain access, but I haven’t received a response yet.)
Thank you in advance for your kind assistance.
