EDA-NIf (EDA NIfTI)

Tool for Exploratory Data Analysis of Neuroimaging Informatics Technology Initiative(NIfTI) format
EDA-NIf creates a dataframe containing meta information of NIfTi file format and provides several useful functions.

Installation

pip install edanif

Beta versions with official documentation are provided starting from major version 1.

Tutorial

We provide tutorial notebooks for all the features we offer. We plan to provide additional docstrings or documentation from the official distribution version (major version 1 or higher).

1. Main-tutorials: https://github.com/DSDanielPark/EDA-NIf/blob/main/tutorials/edanif_tutorial.ipynb
2. Sub-tutorial-folder: https://github.com/DSDanielPark/EDA-NIf/tree/main/tutorials

Main Feature

edanif.eda_nif.meta_df

If you enter only the top-level folder containing nifti files, you can get a data frame for all nifti files.

1. In case of raw nifti files

   import edanif
   
   raw_nifti_folder= '../data/raw_nifti'
   df_raw_nii = edanif.meta_df(raw_nifti_folder, 'nii.gz', 'df_raw_nii_meta.csv', False)
   

   result dataframe: https://github.com/DSDanielPark/EDA-NIf/blob/main/tutorials/result/df_raw_nii_meta.csv

2. In case of mask nifti files (binary files only)

   import edanif
   
   mask_nifti_folder= '../data/mask_nifti'
   df_mask_nii = edanif.meta_df(mask_nifti_folder, 'mask.nii.gz', 'df_mask_nii_meta.csv', True)
   

   result dataframe: https://github.com/DSDanielPark/EDA-NIf/blob/main/tutorials/result/df_mask_nii_meta.csv
