Scripts go in the scripts directory.
Library code (Python modules) goes in the findoutlie directory.
You should put the code in this findoutlie directory on your Python PATH.
This README file has instructions on how to get, validate and process the data.
git clone [email protected]:nipraxis-fall-2022/diagnostics-NME.git
cd diagnostics-NME
Make sure to install everything listed in 'requirements.txt' using 'pip':
pip3 install --user scipy matplotlib pandas scikit-image sympy nibabel jupyter ipython jupytext nipraxis okpy
cd data
curl -L https://figshare.com/ndownloader/files/34951650 -o group_data.tar
tar xvf group_data.tar
First check if the hash_list.txt is added or not
git status
if there is no modification, it means the hash_list.txt is already added to git Else, add the hash_list file to Git:
git add data/group-*/hash_list.txt
git commit -m "Add hash list file"
Change directory back to root of repository
cd ..
python3 scripts/validate_data.py data
To do this, first install the Flit Python package manager: Flit is a system for configuring and installing modules. You may be able to moit the --user below
python3 -m pip install --user flit
Next install the module using Flit. Here the command differs on Windows compared to Linux or macOS.
For macOS and Linux:
(See below for Windows command) Use Flit to install the module.
python3 -m flit install --user -s
For Windows: (See above for macOS and Linux) Use Flit to install the module.
python3 -m flit install --user --pth-file
Now test that you can import the 'findoutlie' module by running the command. The -c flag tells Python to run the code that follows the -c flag.
python3 -c 'import findoutlie'
This should give no error, because the previous step installed the 'findoutlie' directory module to somewhere on Python's search path.
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
identified as an outlier. 0 refers to the first volume. For example (these
outlier IDs are completely random, for illustration):
