+* The read depth input files for filterHD and cloneHD can be generated from a bam-file with samtools. Given a bed file of non-overlapping 1kb windows, e.g.
+
+        human-genome.1kb-grid.bed :
+

+        ...
+
+  For 10 kb windows, you would use `$ awk '{print $1,$3,int(0.5+$4/10000.0),10}` etc. For windows smaller than 1kb, the observations might not be approximately independent.
