R plot doesn't seem right

JennyCNS opened this issue · 5 comments

Hello,

I am running the following script
#estimate best k
sh $MERQURY/best_k.sh 1089729222
#19.9928 so 20

# 1. Build meryl dbs
meryl k=20 count fEpiCoi_cnag1_curated_primary.no_mt.fa output hamour-genome-job.meryl threads=9 memory=130

#2. merge output
meryl union-sum ./hamour.meryl output hamour.meryl

$MERQURY/merqury.sh hamour.meryl fEpiCoi_cnag1_curated_primary.no_mt.fa test1

when I merge the files together I still have a lot of files in the folder,
image

and my plots look like this

test1 fEpiCoi_cnag1_curated_primary no_mt spectra-cn fl

Is there any way you can help me with figure out what is wrong with the analysis?

Thank you,

Jennifer

Oh wait, I am running the fasta file as an input. This will not work will it?

Hello, in this step:

 # 1. Build meryl dbs

You need to use the reads (fq or fa) not the assembly.

Also you could skip

#2. merge output
meryl union-sum ./hamour.meryl output hamour.meryl

If there is only one meryl file to merge :)

Best,

Hi, I am really sorry for being a pain again but should I merge my forward reverse fastq files for the analysis or just trim the adaptors?

Thank you

The k-mers will be cleaner after adapter trimming.
And yes, merge (union-sum) the fastq files.

@JennyCNS feel free to re-open if you need more help!
I've noticed meryl v1.4 had an issue in meryl-lookup, so please use v1.4.1 release instead..!!
