Parameters | Import | Bin Size

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.
