@@ -3,13 +3,18 @@ This repository contains a set of tests which can be run via
 installation.
 
 
+Note that many tests are dependent on various benchmark data sets which are
+hosted internally at FMRIB, and thus cannot be executed outside of the FMRIB
+computing system.
+
+
+Note also that some tests (e.g. `fsl_course/fdt/bedpostx_gpu/`) need to be run
+on a CUDA-capable machine.
+
+
 Run the tests from the repository root as follows:
 
     pyfeeds -c pyfeeds_config.cfg -o /path/to/output_direcfory .
 
 Before running the tests, make sure to update the paths in
 `pyfeeds_config.cfg`.
