abyss error

Actually, you might be a little more careful and change the first sed command to:

sed 's/:N:/ /'

Thanks, I will try

I think so. From the documentation, either the names have to be the same, which they aren't, or you need a /1 and /2 to end them.

You could use sed to fix them something like:

The following should fix it sed 's/:N/ /' INFILE | awk '{print $1}' | sed -e 's|_1|/1|' -e 's|_2|/2|' > OUTFILE

For example, the first two paired reads in fasta file were displayed with head:
>HWI-ST1280:130:C1GYVACXX:8:1101:1161:2106_1:N:0:GGCTAGA
>HWI-ST1280:130:C1GYVACXX:8:1101:1161:2106_2:N:0:GGCTAGA
which were transformed from fastq file.

Is this the problem?

[Wallysb01]

Do your reads have /1 and /2 after them? Otherwise, I don't think ABySS can understand the paired information.

By the way, the other output seems fine. No error report else was found.

Hi,
Here is the script i used.

for k in {56..60}; do mkdir k$k; cd k$k; abyss-pe k=$k name=scale in='/scratch/zjr/scale/data/trimedpaired.fasta' OVERLAP_OPTIONS=--no-scaffold SIMPLEGRAPH_OPTIONS=--no-scaffold E=1 n=10 v=-v; cd ..; done

[Wallysb01]

That seems very odd. What was the command line that got you this far and the rest of the output?

Also, the ABySS user group is usually pretty helpful. So you might try there too.

Hi,
I am doing an ABySS assembly recently. Here is the problem i met:

error: the histogram `scale-3.hist' is empty

Could anyone help me figure this out?
