## Description This dataset belongs to the paper "Encoding of continuous perceptual choices in human early visual cortex" by Barbieri, Töpfer et al. (2023), currently available as a preprint https://www.biorxiv.org/content/10.1101/2023.02.10.527876v2. The data directory consists of the following main folders: - **eye_tracking_for_GPR**: Contains eye-tracking data for participants, organized by participant IDs. - **fmri_data**: Contains various subfolders related to fMRI data analysis and regions of interest (ROIs). The subfolders include: - **ROIs**: Holds results and masks related to regions of interest, data are organized in various subfolders: - **early_visual**: Includes the results of the spatially normalized early visual roi defined as a combination of functional localizer and structural information. - **mt_individual_masks**: Holds results from the second-level localizer analysis for the middle temporal (MT) region of participants, organized by participant IDs. - **parietal**: Includes ROI masks for different parietal regions (inferior parietal lobule, intraparietal sulcus, and superior parietal lobule). - **results**: Contains various analysis results and files related to ROI analysis, including CSV files and JASP analysis files. - **xclass_individual_masks**: Consists of individual masks for model-generalization analyses, organized by participant IDs. - **trialwise_glm**: Contains trialwise general linear model (GLM) analysis results for each participant, organized by participant IDs. Includes beta maps, mask files, and other related files. ***NB: Fore storage limits reasons the trialwise glm data related to s340,s341 and s344 are included in zip files located in the project component [trialwise_glm](https://osf.io/4hmy5/files/osfstorage)*** - **logfiles_experiment**: Contains behavioral and eyetracking logfiles for the experiment. Includes the subfolders: - **behavior_and_eyetracking**: contains logfiles for each participant, organized by participant IDs. Files include fixation metadata and specific logfiles for different MRI sessions. - **simulation**: Holds simulation-related files related with the analyses described in Appendix 2 of the manuscript. ## Instructions Researchers can navigate the structure to access specific data files and analysis results for further investigation. To reproduce the main analyses described in the paper: - Create a project folder on your computer. - Download the [data directory](https://osf.io/vcmdg/files/osfstorage) on your project folder. - Download the [zip files](https://osf.io/4hmy5/files/osfstorage) included in the *trialwise_glm* project component and extract the content in the corresponding *data/fmri_data/trialwise_glm* folder. - Clone the [Github repository](https://github.com/RiccardoBarb/GPR_fMRI) containing the scripts to perform the analyses in your project folder. - Refer to the official codebase publicly available on github: https://github.com/RiccardoBarb/GPR_fMRI to get started on the analysis of data.
