Diagnostics project

Script go in the scripts directory.

Library code (such as Python modules or packages) goes in the packages directory.

You should put this packages directory on your Python PATH.

This file has instructions on how to get, validate and process the data.

Get the data

cd data
curl -LO http://nipy.bic.berkeley.edu/psych-214/group01.tar.gz
tar zxvf group01.tar.gz
cd ..

Check the data

python3 scripts/validate_data.py data

Find outliers

python3 scripts/find_outliers.py data

This should print output to the terminal of form:

<filename> <outlier_index>, <outlier_index>, ...
<filename> <outlier_index>, <outlier_index>, ...

Where <filename> is the name of the image that has outlier scans, and <outlier_index> is an index to the volume in the 4D image that you have indentified as an outlier. 0 refers to the first volume. For example:

group01_sub01_run1.nii 3, 21, 22, 104
group01_sub02_run2.nii 11, 33 91
group01_sub04_run2.nii 101, 102, 132
group01_sub07_run2.nii 0, 1, 2, 166, 167
group01_sub09_run2.nii 3
