Hi @jeongmeani ,
Not an author of CNVkit, but as far as I know the CNVkit's scatter plot is a mere representation of the data contained in ".cnr" and/or ".cns" files (so are most CNVkit's nice plots)
To diagnose a possible issue, could you please give also details about:
batch
? Each pipeline step separately?) + exact parameters you used for each sub-command
Thanks. Have a nice day. Felix
Hi, Felix.
sorry for late reply.
i let you know about information you request.
yes, i ran using command batch
and my sub-command is like below
1) cnvkit.py batch {Tumor-BQSR.bam} --normal {Normal-BQSR.bam} \
--targets $bed \ --fasta hg19.fa --access /data/tools/CNVkit_install/data/access-5k-mappable.hg19.bed \ --output-reference ref.cnn --output-dir $CNV_kit_dir
2) cnvkit.py scatter -s $CNV_kit_dir/$Sample_N'.BQSR.cn'{s,r} --y-max 10 --y-min -10 -o $CNV_kit_dir/$Sample_N'.png'
also, i made scatter plot of normal cnr and cns file reflecting normal.ref.cnn. but this plot too weird. i guess that this plot should be shown more clear like this?
but the plot is shown like below
can you recommend anything?
Best regards
Jeongmin
Thanks @jeongmeani ,
--drop-low-coverage
in your batch
command?
=> In this other part of CNVkit's documentation, it is adviced to remove such low covered bins
=> This is my strongest hint, give it a try and tell us what you get?Hi, Felix.
Sorry for late reply.
--drop-low-coverage
option, but there is no change.so, would you recommend anything of this?
Best Regards

Hi @jeongmeani ,
Sorry I run out of ideas...
=> Try to update to a newer version of CNVkit (v0.9.9) ? (+ try with/without --drop-low-coverage
?)
=> This could be linked to an issue fixed since your version
=> Or simply a known issue on WES datasets? Unfortunately I am not expert enough to tell..
Have a nice day. Kind regards. Felix.
Hello @jeongmeani ,
Any news since last time ? => I do not know if @tskir saw this and can maybe have any idea?
Have a nice day. Kind regards. Felix.
Hi,
Using cnvkit, i made cnv scatter plot. but the plot is weird like below.
i expected the plot to be more clear in y-axis plot like below
why does this image have this noise?
Best regards
