 ### Introduction of Calder analysis for other genomes
 
-Although Calder was mainly tested on human and mouse dataset, it can be appliabled on dataset from other genomes. One additional information is required in such case: a `feature_track` that presumably having higher values in A than in B compartment. Some suggested tracks can be gene density, H3K27ac, H3K4me1, H3K4me2, H3K4me3, H3K36me3 (or negative transform of H3K9me3 signals)

One additional information is required in such case to determine which branch on the hierachcal tree to be assigned as `A` compartment: a `feature_track` that is presumably positively correlated with compartment score (or higher values in A than in B compartment). Some suggested tracks are gene density, H3K27ac, H3K4me1, H3K4me2, H3K4me3, H3K36me3 (or negative transform of H3K9me3) signals.
