 **The strategy**: given a `bin_size` specified by user, we call compartments with extended `bin_sizes` and choose the smallest `bin_size` such that no bigger `bin_size` can increase the compartment correclation with a reference compartment more than 0.05. For example, if correclation for `bin_size=10000` is 0.2 while for `bin_size=50000` is 0.6, we are more confident the latter is more reliable; if correclation for `bin_size=10000` is 0.5 while for `bin_size=50000` is 0.52, we would choose the former as it has higher resolution.

 ### Introduction of CALDER analysis for other genomes
 
-Although CALDER was mainly tested on human and mouse dataset, it can be applied on dataset from other genomes. One additional information is required in such case: a `feature_track` that is presumably positively correlated with compartment score (thus higher values in A than in B compartment). This information will be used for correctly determing the `A/B` direction. Some suggested tracks are gene density, H3K27ac, H3K4me1, H3K4me2, H3K4me3, H3K36me3 (or negative transform of H3K9me3) signals. Note that this information will not alter the hierarchical compartment/TAD structure, and can come from any external study with matched genome.

 `feature_track` should be a data.frame or data.table having 4 columns (chr, start, end, score), and can be generated directly from conventional format such as bed or wig, such as the following example:
