Hi,

Could you help me about the bowtie2 error message below that I don’t understand? I run HiC-Pro (Servant et al., 2015) for our chicken HiChIP data (Mumbach et al., 2016) with 40bp paired-end reads. HiC-Pro is an aligner based on bowtie2. After running, bowtie2 showes error message below. Could you help me? Please let me know if you need any information. Many thanks.

This seems like an issue with your installation of bowtie though I am not exactly sure of this. You could get around this by using any other HiC tool that uses an aligner that is not based on bowtie2 or that can directly use output of bowtie2 run independenly.

Try using HiCexplorer (link) This package is able to use read aligners different from bowtie2 namely hisat2 and bwa. The authors are very helpful if you contact them and bwa and hisat2 are very versatile aligners to use. Hope this helps -Ashwin
