I am try to run a package called lofreq,  and for some reason nim is not working properly.

 ./lofreq viterbi -f=/home/guest1/Desktop/HSA_chr/KY962518_tandem_union.fasta -b='/home/guest1/Desktop/UL_guppy4/HG002_ultra_tandem_filterK.bam' > '/home/guest1/Desktop/UL_guppy4/HG002_ultra_tandem_filterK_viterbi.bam'

I am using nim-1.4.2.

I have clean the cache, and it still does not work. 

There is anything else that you suggest?
