Invalid daa file

**Hi everyone, **

This is my first time in Megan,
I and running shotgun data using paired-end reads

I used this
###1.Install Megan
MEGAN_Community_unix_6_18_0.sh

###2.This file in neccesary is we want meganizer
megan-map-Oct2019.db

###3.Download and install DIAMOND

###4.Download the NR database from here
ftp://ftp.ncbi.nih.gov/blast/db/FASTA/nr.gz

###5.Build a DIAMOND index
diamond makedb -d nr --in nr.gz

###6.This results in an index file
nr.dmnd

###7.Run DIAMOND (in query we use the name of our sequences) - ESTO SE DEMOR√ď CORRIENDO 15 D√ćAS
diamond blastx --db /vault2/bioinfDBs/diamondDB/nr.dmnd --out reads_shotgun.daa \ --outfmt 100 --query /vault2/homehpc/voteroj/SEQ_SHOTG/T4P4_T1_TCCGCGAA-GTACTGAC_L004_R2_001.fastq.gz

###8.This will produce a DAA file called
reads_shotgun.daa

###9. Before run MEGANIZER, we need the following database, we can download from Megan website:
###The following file maps NCBI-nr accessions to taxonomic and functional classes (eggNOG, InterPro2GO and SEED), unzip before use:

megan-map-Oct2019.db.zip

And then when I tried to meganizer using this script:
nohup /vault2/soft/bio/megan6/tools/daa-meganizer -i reads_shotgun.daa \ -mdb megan-map-Oct2019.db -v &

The result obtained; attached at the end of the message; I do not how to figure out, Do you have any suggestion, please.

**Thanks in advance, **
Best regards,
Vanessa O.J.

MEGAN is reporting that the file may be incomplete… Could you please try running the diamond view command on the file to see whether diamond also reports an incomplete file.

**Hi Daniel, thank you for your answer, I run this, I don’t know if is the correct way, **

diamond view --daa/-a reads_shotgun.daa --out/-o reads_shotgun_final.daa --outfmt/-f 100 --compress 1

But, the answer was

Error: Invalid option: daa/-a

My file reads_shotgun.daa has 217.363.456 KB.
Thanks in advance.

Vanessa
