unravel.cluster_stats.find_incongruent_clusters module#

Use cstats_find_incongruent (cfi) from UNRAVEL if cstats_fdr was used to convert non-directional p value maps into directional cluster indices. This helps to find clusters where the direction of the mean intensity difference between groups does not match direction of the difference in cell/label density between groups.

Input:

  • ./_cluster_validation_info/tukey_results.csv or ttest_results.csv from cstats

  • Columns: ‘cluster_ID’, ‘comparison’, ‘higher_mean_group’, ‘p-value’, ‘significance’

Output:

  • Cluster IDs where the mean intensity difference does not match the density difference between groups A and B.

Note

  • This is modules is useful to find clusters where z-scoring introduces incongruencies between the mean intensity difference and the density difference.

  • For example, if group A has increased IF in region A and not B, z-scoring may decrease the relative intensity of region B.

  • This decrease for region B for one group, may introduce a difference in the mean intensity between groups that is not reflected in the density difference.

Usage:#

cstats_find_incongruent -c tukey_results.csv -l groupA -g groupB [-v]
