Fail loading index ('dna_compression.bin' file is empty)

[jaudoux]

Dear HPG developpers,

I am experiencing some trouble to execute HPG-aligner on RNA mode. The following error quickly shows up during the execution :

Fri Feb 5 11:27:43 2016 FATAL lib/hpg-libs/bioinfo-libs/aligners/bwt/genome.c [413] in load_binary_dna(): Error, '/data/indexes/HPG//GRCh38//dna_compression.bin' file is empty!

This is the command line I have been using:

hpg-aligner rna -i /data/indexes/HPG//GRCh38/ -t 20 -o hpg -f simulation/reads_1.fastq.gz -j simulation/reads_2.fastq.gz -z

The index has been constructed using the SA (default) mode, this is the content of my index directory:
