Issue with obligate_essentiality_analysis.R

[wgharib]

Hello, I was trying to use Tn-seq doccker version on my dataset and I 'm stuck with the following error

Error:

Error in mutate_impl(.data, dots) :
  contrasts can be applied only to factors with 2 or more levels
Calls: %>% ... mutate -> mutate_ -> mutate_.tbl_df -> mutate_impl -> .Call
Execution halted

To replicate the error here is the needed files:

TSV files created with khturner/tn-seq process_reads.py attached
gff file attached
reference genome attached
