Hi pgarcia,

The .broadPeak format is not a currently supported file format in IGB, however it can easily be converted to the more common .bed format, which is supported.

To convert the file to a bed file, limit the data to the first 6 columns. To do this on the command line use:

$cut -f1-6 FILE.narrowPeak > NEWFILE.bed

Optionally, you can replace the score field (column 5) with any one of the latter fields (columns 7-9 from broad peak format) to make that value appear as the score.

These file formats (both broadPeak and narrowPeak) have been recently requested by users, and we are preparing to add support for them in the near future.
