   - **labels**: This file contains a binary label that has been assigned to each training, validation and test input data point. (Must be 0/1).  
 
   - **chromatin_tracks**: Multiple chromatin files can be passed to Bichrom through the YAML file. (The YAML field chromatin_tracks accepts a list of file locations.) Each line in a chromatin track file contains tab separated binned chromatin data. The data can be binned at any resolution.   For example, if the genomic windows used to train Bichrom are 500 base pairs, then: 
-    * If bins=50 base pairs, then each line in the chromatin file will contain 10 (500/50) tab separated values. 
-    * If bins=1 base pair, then each line in the chromatin file will contain 500 values. Note that all chromatin feature files that are passed to Bichrom must be binned at the same resolution.
