 * Question: should we store the sampling rate and hardware info in the database?
 
 ## FIXMEs
-* repro must have foreign keys to dataset and subject
+* repro must have foreign keys to dataset **and** subject
 * Dataset finding samplerate in stimuli.dat can be improved
+* Reading fi data from old-style directories
+* maybe delegate this to Stimulus?
+* implement alternative dataSources, somehow 
+* stimulus contrast is not read from nix file (e.g. filestimulus) maybe a problem with all mutables?
+* Add relacs_nix_version to dataset, could be used to decide how to read stuff, in particular, we will switch to DataFrames for most features after nixio version 1.5
