computeMatrixOperations can perform a variety of operations on one or more files produced by computeMatrix (N.B., the output is always written to a new file):
| Subcommand | What it does |
| info | Prints out the sample and region group names in the order in which they appear. |
| subset | Subsets a file by the desired samples/region group names. This can also change the order of these samples/region groups. |
| filterStrand | Filters the file to only include regions annotated as being on a particular strand. |
| rbind | Concatenates multiple matrices together, top to bottom. |
| cbind | Merges multiple matrices, left to right. |
| sort | Sorts the given file so regions are in the order of occurence in the input BED/GTF file(s). |
| dataRange | Returns the min, max, median, 10th and 90th percentile of the matrix values per sample. |
These operations are useful when you want to run computeMatrix on multiple files (thereby keeping all of the values together) and later exclude regions/samples or add new ones. Another common use would be if you require the output of computeMatrix to be sorted to match the order of regions in the input file.
