+### PAM50 Levels
+
+These level files are a slightly modified copy of the [level files](https://github.com/PhillipsLab/pam50/tree/main/Spinal%20Cord%20Levels%20NIfTI) produced by the [Phillips Lab](https://github.com/PhillipsLab): 
+
+Modifications include:
+
+- Change data type from float64 to float32
+- Copy header from current PAM50/spinal_levels 
+- Rename files
+
+To reproduce the modified files, please run `git checkout e854bbad9ab550fd93acabeaf43c97cf66b3a4e5`, then run the following script in your terminal:
+
+```bash
+#!/bin/bash
+#
+# Process Phillips Lab PAM50 spinal levels to match existing PAM50 conventions.
+#
+# Usage:
+#   ./process_spinal_levels.sh
+# 1. Clone https://github.com/spinalcordtoolbox/PAM50
+# 2. Checkout commit e854bbad9ab550fd93acabeaf43c97cf66b3a4e5
+# 3. Run inside /PAM50/spinal_levels_PhillipsLab/
