The data for this section of the project are from the CamCan project, and can be requested from: http://www.cam-can.org/ The data were first processed using the matlab script [processMRIdata.m][1] This script requires a working FSL installation which can be obtained at: https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/ The script also requires the file [v1mask.nii][2], which is defines the V1 region of interest as described by Wang et al. (2015): https://doi.org/10.1093/cercor/bhu277 The script [powercontoursMRIeventrelated.R][3] was then used for all further analysis and plotting, to produce [Figure 7][4]. Illustrations of the ROI mask were produced using the HCP [connectome workbench][5] software and are provided here in tiff format ([V1ROIl.tiff][6] and [V1ROIr.tiff][7]). Paths in all scripts will need to be updated to reflect the local directory structure of the computer used for the analysis [1]: https://osf.io/vrkyn/ [2]: https://osf.io/zpr7d/ [3]: https://osf.io/842ej/ [4]: https://osf.io/rqfn9/ [5]: https://www.humanconnectome.org/software/connectome-workbench [6]: https://osf.io/xvkd9/ [7]: https://osf.io/my4zn/
