Searing for viral but bacteria show up  #1160

Description of bug

Hi all,

I did cDNA synthesis to amplify both RNA and DNA viruses and I used NexteraXT (Illumina) to amplify the vrial commmunities and and sequencing with NextSeq500 using a 75cycle kit with paired end 40nt reads and 6nt+6nt dual indexing.
I check the sequence data using Kraken and I can see the viral communities as we spiked some of the samples with known viruses and the data makes sense. However, I was also interested into metaviralspades.py. I was able to generate the data but when I blast the contigs/scafold only pseudomonas aeruginosa shows up (which is a bacteria). I was wondering if I can use spades for my sequence data (as it is 40bp).

I attached the log and parameter file.

I upload my scaffold file too.
