Error running vcf2xg.sh on c. elegans #20

moldach · 2020-05-01T23:10:23Z

First off, I have to say great job on the tool! I've played around with the practice data and now I'm very excited to try this tool out and show it to my laboratory. I've been evaluating ~10 tools for looking at SVs and yours by-far looks the most promising!

I'm getting an error trying to convert a .VCF to .xg using the vcf2xg.sh script on the reference genome (C. elegans) used for alignment.

I tried another call set (Delly) to see if it's something specific to the format of VCF but got a similar error:

Any idea what could be happening here? One thought is that chromosome in H. sapiens are usuallly labeled chr1 but in C. elegans they are labeled (I, II, III, IV, V, X, MtDNA) - not sure if this information helps?

As for the Reference :0-270000000 part I have no idea of the context of this number: 270000000? It seems like a very round number? The entire genome of C. elegans is ~100286401bp.

The text was updated successfully, but these errors were encountered:

6br · 2020-05-02T02:36:54Z

Thank you for the feedback!
As you said, we regarded the input as H. sapiens and thus we used 270000000 as the maximum length as temporally, but, actually we can calculate the actual length. I'll fix it. The latter issue needs further investigation because I have not used Delly as an input. I will tell you if I know something.

6br · 2020-05-05T05:42:24Z

I fixed the truncated reference problem. For the latter data, the gfa file seems to be generated at least. https://github.com/sjackman/gfalint can be used for validation of gfa file.

moldach · 2020-05-06T15:32:33Z

Okay I've remove MoMI-G and pulled in the new version with git clone and then re-ran for Delly.

It's doesn't look like it generated the .gfa file (although there is a .ggf?)

I have the following call sets if you are more familiar with one of them we can try that: CNVnator, DeepVariant, Delly, GRIDSS, Lumpy, Manta, MindTheGap, NGSep, Pindel, Tardis.

6br · 2020-05-07T10:15:12Z

We defined .ggf as a subset of .gfa, so gfalint <output.ggf works.
Sorry I am not familiar with these SV callers since they are for Illumina.

moldach · 2020-05-21T01:44:50Z

I've posted a follow up in the gfalint to show the output of MoMI-G.
If you'd like a more detailed error message I can try a couple other tools:

"You may wish to try another tool that may give a better error message, such as perhaps Bandage if it's GFA1, or Gfapy for either GFA1 or GFA2."

Which format is this in?

I tried Gfapy just now but ran into an issue

Any idea why this odd output is being produced by MoMI-G?

6br · 2020-05-21T04:39:10Z

Is it possible to try it again on the latest MoMI-G master?
MoMI-G tools output is compatible with GFA1 format. I'm sorry that I have no idea why gfapy does not work.

moldach · 2020-05-26T17:26:11Z

Okay making some progress now.

I've tried again off of the latest MoMI-G master (git clone). There is no warning issued if the user forgets to install vg (I did). However, I think I've now done that properly.

cd ~/projects/TEST-MOMIG
wget https://github.com/vgteam/vg/releases/download/v1.24.0/vg
chmod +x vg

And test it's working:

(base) mtg@mtg-ThinkPad-P53:~/projects/TEST-MOMIG$ ./vg
vg: variation graph tool, version v1.24.0 "Montieri"

usage: ./vg <command> [options]

Should I be concerned about the TypeError's?

moldach · 2020-05-26T17:32:35Z

Because the momig-test-output.xg file is there it looks like vg worked. I'm now wondering about the next step.

I need to create a static/ directory in the current working directory and then move the momig-test-output.xg and momig-test-output.pcf into static/ correct?

What about the config.yaml: a configuration file? What is this supposed to look like?

6br · 2020-05-27T07:42:44Z

Actually there is a line in vcf that is not parsed by momig-tools, and I intend to output error message when it encounters such a line. But it won't work now due to a bug. I suppose the output pcf file might be insufficient. I'll fix it soon.

6br · 2020-05-27T08:00:45Z

After that, this configuration YAML file is needed to be loaded as the next step.
https://momi-g.readthedocs.io/en/latest/configure_file.html
The instruction is as follows.
https://momi-g.readthedocs.io/en/latest/quick_start.html#how-to-use-your-own-custom-data

git clone from https://github.com/MoMI-G/MoMI-G.
mkdir static on the directory MoMI-G clones.
Put your XG data in the static folder like static/data.xg.
Add configure file on static/config.yaml.
Modify Docker.backend file.
Build backend server and run.

The fastest way is to copy this config file and change the file name of xg in the following config.yaml.
https://github.com/MoMI-G/MoMI-G_backend/blob/master/sample/chm1/config.yaml

6br · 2020-05-27T08:42:04Z

Is it possible for you to try it on the latest master and tell me the output of MoMI-G script? I suppose the lines starting with Error line: would be output.

So this is the error output:

Okay so I now have a config.yaml file that looks like this:

bin:
  vg: "vg"
  vg_tmp: "vg"
  vg_volume_prefix: ""
  graphviz: "dot"
  fa22bit: "faToTwoBit"
  bigbed: "bedToBigBed"
reference:
  chroms: "static/GRCh.json"
  data:
    - name: "ce11"
      features:
        - name: 'gene_annotation'
          url: "static/c_elegans.PRJNA13758.WS265.annotations.gff3"
          chr_prefix: ""
data:
  - name: "maddog"
    desc: "2020-05-27"
    chr_prefix: ""
    ref_id: "ce11"
    source:
      xg: "static/Celegans.xg"
      csv: "static/Celegans.pcf"
      gam: ""
      gamindex: ""
    features: []
    static_files: []

However, I cannot find an example of GRCh.json file that includes the color and length for every chromosome. Could you please share an example so I can change for my species, thank you.

import json
data = {}
data['chromosome'] = []

data['chromosome'].append({
 'name': 'I",
 'length': 15072434,
 'color': '#4477AA'
})
data['chromosome'].append({
 'name': 'II",
 'length': ,15279421
 'color': '#66CCEE'
})

...

Thank you for reporting an error. I'll check it.
This is an example of chromosome length and color json file.

I suspect this line is invalid.
I 4282001 470_CNVnator_dup_1 4295000 . 13000 DUP GT:CN ./1:2

Usually, vcf file is described as a tab-delimited text as #CHROM POS ID REF ALT QUAL FILTER INFO, but the previous line does not have any REF field (because there are two tab characters between 470_CNVnator_dup_1 and 4295000), which makes the script fail. That's why MoMI-G tools cannot handle well in this VCF dialect.
Do you know where is the specification of this VCF variant?

moldach · 2020-05-28T18:29:13Z

I suspect this line is invalid.
I 4282001 470_CNVnator_dup_1 4295000 . 13000 DUP GT:CN ./1:2

Luckily I have a number of variant call sets from a variety of tools so we can tell if this is unique to CNVnator or not:

For all of the VCF files I have I seem to get an error.

Do you know where is the specification of this VCF variant?

No, I cannot find it on their documentation

6br · 2020-05-29T08:52:34Z

These errors might be caused due to different reasons. MoMI-G tools does not support Illumina SV callers explicitly. Is it possible to normalize each vcf file with https://github.com/fritzsedlazeck/SURVIVOR before running vcf2xg? (e.g. run SURVIVOR merge file_list.txt 0.1 1 1 1 1 50, and file_list.txt just includes the file name of vcf).

moldach · 2020-05-29T18:31:33Z

I was just working with SURVIVOR the other day so it was quick to generate:

From file_list.txt that looks like:

breakdancer.vcf
cnvnator.vcf
deepVariant.vcf
delly.vcf
gridss.vcf
lumpy.vcf
manta.vcf
mindTheGap.vcf
ngsep.vcf
pindel.vcf
tardis.vcf

Merge:

merging entries: 59

Tried using SURVIVOR to just merge two files, delly and pindel, and I get the same error.

6br · 2020-05-30T13:51:08Z

SURVIVOR seems to add "chr" as a prefix of each reference genome to normalize, but the original reference genome is started with I, so chrI is failed to detect.
Anyway I am looking for the way to normalize VCF file from various kinds of SV callers.

fritzsedlazeck · 2020-06-12T22:41:04Z

Please update SURVIVOR.

I am not 100% sure which subcommand of SURIVOR is used, but I assume the merge .
This behavior in merge has been updated a couple of months ago.

Thanks
Fritz

I also have similar error, like this:

And my vcf files were merged with bcftools merge.

6br · 2020-07-14T06:55:16Z

Thank you for reporting. I assume some records in the vcf file are not supported in vcf2vg. I updated the way to report errors on ./scripts/vcf2gfa/gfa_generator.rb.
