Hello! So the PING pipeline has not been tested or validated for WES data. There are a couple roadblocks to implementing WES analysis because PING relies on intronic sequence to differentiate between similar alleles.
However, WGS is a different story, and we just made adjustments to PING to be able to handle WGS data, specifically 1000 Genomes Project data, which can be found in the wgs_snakemake branch. (the publication detailing these changes is pending)
However, since your data is much higher depth then 1000GP, I would recommend staying with the normal workflow as you have done, but there are two important considerations to take into account.
First, we have noticed that our extraction step does not work very well for WGS data. Specifically, there seems to be parts of the genome that have high sequence similarity to an intronic region of KIR3DL2, causing a huge pileup of of misaligned reads that get brought into the workflow. The effective strategy that we used with the 1000GP data was to extract from the aligned cram files (aligned to HG38), generate fastq files from the extracted reads, then send those reads through the PING workflow. The BED file used for extraction can be found here https://github.com/Hollenbach-lab/PING/blob/wgs_snakemake/Resources/1000Genomes_resources/kir_regions.bed. I don't know if you have HG38 aligned cram of bam files, but doing the extraction this way generates much cleaner data.
Second, it is really important to separate out the data by ethnicity for copy number determination. Because the allelic makup of KIR differs so much between ethnicities, having a mixed group can jumble up the copy number results and lead to incorrect genotype calls.
With those points out of the way, looking at the output you provided it looks like you are only sending a single sample through. For the copy number determination step, it needs multiple samples to differentiate between copy number groupings. If this is the only sample you have, then id suggest first doing the BAM/CRAM extraction based on the bed file i linked previously, then share the copy number graphs with me and i can help determine the copy numbers.
Thanks a lot for your hardworking on PING. I was trying to use my WES and WGS data to do KIR genotyping, but it returned with partial results. manualCopyNumberFrame.csv and finalAlleleCalls.csv are not found in the output directory. Both my WES and WGS data are over 100X (yes, the WGS data is also 100X and I think the coverage should not be a problem). And I found your paper published in 2016 also used WES or WGS data to validate this pipeline. So WES or WGS should be OK, right?
I attach part of my rstudio console for your reference:
