Bin Size
Specify a bin size to use when summarizing read counts within equally spaced sets of contiguous base pairs on each chromosome .
The Bin Size parameter specifies the number of base pairs across which you want to summarize read counts.
Caution : Importing SAM files can be computationally intensive if a small bin size is specified here, especially when a bin size of 1 is specified for the purpose of summarizing read counts for all positions in a genome .
