Error

[ratheraarif]

The execution of the following code generates some error when I execute it on my own hic data. Please note that the hic files that I am working with have chromnames as chr1, chr2,...

  aggr <- aggregate(.x, centros_pairs, maxDistance = 1e999)
  plotMatrix(
    aggr, use.scores = 'balanced', limits = c(-5, -1), 
    cmap = HiContacts::rainbowColors(), 
    caption = FALSE
  ) + ggtitle(.y)
}) ```

Error in `map2()`:
ℹ In index: 1.
ℹ With name: WT.
Caused by error in `validObject()`:
! invalid class “GRanges” object: 
    'seqlevels(seqinfo(x))' and 'levels(seqnames(x))' are not identical
Run `rlang::last_trace()` to see where the error occurred.

please suggest any help with the code example too

[js2264]

This error mostly comes from the chromosome names used in your imported HiC data, compared to the chromosome names used in centros_pairs. Can you confirm they are all the same (table(seqnames(regions(centros_pairs)) %in% seqnames(regions(.x))))?
