Wiki Version:
This project is published in the journal NeuroImage at https://doi.org/10.1016/j.neuroimage.2019.116328 `BIDS_40um/sourcedata/` contains the original left and right hippocampal block nifti images (ftp://bigbrain.loris.ca/BigBrainRelease.2015/2D_Final_Sections/Coronal/Png/Full_Resolution/), which is publically available under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International Public License (https://bigbrain.loris.ca/main.php?test_name=license). BIDS_downsampled/sourcedata contains 80um resampled blocks, on which manual labelling of hippocampal and surrounding structures was performed (`BIDS_downsampled/manual_masks/`). Laplacian solutions were obtained over the domain of hippocampal grey matter according to our previous publication (https://www.ncbi.nlm.nih.gov/pubmed/29175494), code available at https://github.com/jordandekraker/HippUnfolding (`BIDS_downsampled/HippUnfold`). These solutions were obtained in the downsampled image space due to memory limits, and were then upsampled via the `upsample.m` script, which populated the corresponding directories in `BIDS_40um`. In parallel, an equivolume laminar solution was also obtained over the domain of hippocampal grey matter using code available at https://github.com/nighres/nighres. The exact code used to obtain these solutions can be found in BIDSscripts/nighres. All analyses performed in the current publication can be replicated using the scripts found in BIDSscripts. Many of these scripts depend on the outputs from other scripts. For example, `allfeatures.m` collects, preprocesses, and plots the 5 morphological features computed in `MorphologyFeatures.m` as well as the 10 laminar features computed in `LaminarFeatures.m`. For ease of use, `.mat` files are provided alongside each script containing all variables needed to run downstream analyses. `BIDSscripts/figures` contains visualizations of all analyses, as well as supplementary analyses and some which were not included with our publication because no conclusive assertions could be made form them.
