Error cannot open file

[akhwela]

I am trying to taxonomically classify my reads using only the viral database. This is the code I used:

kaiju -t /home/akhwela/kaijudb/viruses/nodes.dmp -f home/akhwela/kaijudb/viruses/kaiju_db_viruses.fmi
-i home/akhwela/lustre/Data/noSheepQCRead/*.fastq.gz

I keep getting errors that specify the input files cannot be opened sometime it also says the nodes.dmp file cannot be opened. I have tried to run the code on a single input file but it still give the same error please assist.
