Why homer makeTagDirectory output an empty TagDirectory

Question

[xiaoyonf]

I am trying to analyze Hi-C data using Homer4.11. I am stuck in the step of makeTagDirectory. After trim and bowtie2 alignment, I used the basic argument of makeTagDirectory according to the instruction. However, each time I got an output TagDirectory with all the files with tags.tsv extension are empty. Could anyone offer any suggestions? Thanks!
