Hello everyone,

I'm running Mira in reference based mode and I face the following problem:

Read HWI-D00173:80:C42H0ACXX:8:1101:1295:2161 is present more than once in the
data set. Did you load a file twice in the manifest? Is a read present more
than once in your file(s)?
……..

More than 2000 cases like the above, will not report more. Fix your input!


This problem occurred when I tried to run Mira with fastq files that were
corrected by SPades.
I search some of the reads but are unique reads in the files (I'm using paired
end reads)
the only difference that I noticed with the "original" read files is the
following:
Original file:

@HWI-D00173:80:C42H0ACXX:8:1101:1295:2161
CCCCTGTCCACTTCTCTGTGAAAATGAGGGTAATTGACATGATTTCTGTCCCTTTCTATGTGCTTCCATACGTTTATAGAAACCTGTACAGAAG
+

corrected reads file:

@HWI-D00173:80:C42H0ACXX:8:1101:1295:2161
CCCCTGTCCACTTCTCTGTGAAAATGAGGGTAATTGACATGATTTCTGTCCCTTTCTATGTGCTTCCATACGTTTATAGAAACCTGTACAGAAG
+HWI-D00173:80:C42H0ACXX:8:1101:1295:2161

The only difference is that after the "+" spades corrector has copied the name
of the read.
Could be the reason that Mira complains?

Thank you very much,
Vasilis.
