0

Entering edit mode

I am using a5 Miseq pipeline but facing error while running example files of phix as well as sample files. [a5] ERROR:Unable to identify any properly paired reads [a5] ERROR: Please check that you have provided at least one library of paired-end reads with names conforming to the Illumina read pair convention.

Kindly help me out!

And what is the output of:

awk 'NR%4==1' /home/ambrina/a5_miseq_linux_20160825/example/phiX_p1.fastq | head

And

awk 'NR%4==1' /home/ambrina/a5_miseq_linux_20160825/example/phiX_p2.fastq | head

I asked for the output of the commands:

awk 'NR%4==1' /home/ambrina/a5_miseq_linux_20160825/example/phiX_p1.fastq | head

And

awk 'NR%4==1' /home/ambrina/a5_miseq_linux_20160825/example/phiX_p2.fastq | head

But anyway, the problem is with the SGA binary from A5_MiSeq:

sh: 1: /home/ambrina/a5_miseq_linux_20160825/bin/sga: Permission denied

If you are luck it is just a matter of setting sga execute permissions, but you may even have to recompile it.
