unionbedg -header not working

[GregorD96]

Dear all,

thanks for the excellent toolkit!

I am currently running bedtools v2.30.0 and tried to merge several bedraphs using bedtools unionbedg. However, the option -header doesn't seem to provide any header information beyond the first three columns:

chrom start end cc6m_2244_T7_ecorv 45 46 0.00 0.00 0.00 cc6m_2244_T7_ecorv 48 49 50.00 75.00 45.45 cc6m_2244_T7_ecorv 49 50 N/A N/A 100.00 cc6m_2244_T7_ecorv 51 52 50.00 50.00 57.89

according to the man page, I expected the remaining columns to be filled by filenames.

Best,

Gregor
