Error in running fermikit

[Addicted-to-coding]

When I try to run the software using: fermi.kit/run-calling -t16 ~/reference.genome/chr19_new.fa prefix.mag.gz | sh, I get the error ERROR: failed to locate the BWA index. Please run 'fermi.kit/bwa index -p ~/reference.genome/chr19_new.fa ref.fa'. When I run this command on my .fa file, I get the error [user@login2 test_fermikit]$ fermi.kit/bwa index -p ~/reference.genome/chr19_new.fa a.fa [bwa_index] Pack FASTA...
