Bedtools maskfasta error - std::out_of_range

Hello everyone!

I'm using bedtools maskfasta in a pipeline that I run on many genomes.

I have 2 genomes that don't run.. They are large plant genomes, and I had to cut some of the chromosome in 2 (after 2Go, that was the limit of my other tool) to run another analysis in which I identify transposable elements. Everything is formatted the same as you can see

My genome identifiers: genome.fasta

>Ptabu_chr_10
>Ptabu_chr_1-1
>Ptabu_chr_11
>Ptabu_chr_1-2
>Ptabu_chr_12
>Ptabu_chr_2-1
>Ptabu_chr_2-2
>Ptabu_chr_3-1
>Ptabu_chr_3-2
>Ptabu_chr_4-1
>Ptabu_chr_4-2
>Ptabu_chr_5-1
>Ptabu_chr_5-2
>Ptabu_chr_6
>Ptabu_chr_7
>Ptabu_chr_8
>Ptabu_chr_9

And an example of my gff file: sirevirus.fasta

This file was produced on the previous genome file, so the elements found are within the range of the chromosomes.

Ptabu_chr_11    MASiVE  Sirevirus   1647309169  1647317981  .   -   .   ID=Ptabu_chr_11-P-1647309169;length=8813;age=1.9846

The command line:

bedtools maskfasta -fi ../genome.fasta -bed ../sirevirus.fasta -fo genome.fasta_all_fulllength_masked.fasta

The error I get is:

terminate called after throwing an instance of 'std::out_of_range'
  what():  basic_string::substr: __pos (which is 3505698666) > this->size() (which is 2000000000)

I ran only chr 5-2 of this species as a test and there was no issue. The output created by maskfasta only appends 2 chromosomes before it crashes. The position in the error message '3505698666' doesn't exist in my data, no chromosome is that big.

I have the same issue on the garlic genome which is 14Go and one chromosome was cut, but it runs perfectly fine in wheat which is also 14Go but with smaller chromosomes.

If anyone can help me, I would greatly appreciate it!

Thank you :)

what is the longest position in the bed/gff ? what is the longest chromosome in the fasta ?

also, if you have gdb (GNU debugger) please, run

$ gdb /path/to/bedtools
> run  maskfasta -fi ../genome.fasta -bed ../sirevirus.fasta -fo genome.fasta_all_fulllength_masked.fasta

wait for the error, type backtrace and show us the output

I don't think it crashed. Just stopped at the same point it's been stopping when trying to run it.

sadly, bedtools was compiled without debugging option. there is not useful trace here.

this error seems due to any of the chrom size with 2000000000, Ptabu_chr_5-2 is fine doesn't tell anything. it doesn't look like a memory issue(usually would see "segmentation fault" if it's memory)

I would suggest 1) check whether the .fai file is right, also check whether regenerate .fai file would work. 2) You might need split the fasta into chroms and split .gff file into pieces try to narrow down to the lines cause the trouble, sometime the format might be wrong.

I've been running several times several of the chromosomes individually instead of the whole genome in one go and I can't reproduce my original error. I do encounter a new error with blast on the next step, but the only error I have is "Program failed, try executing the command manually.". It doesn't work on 2Go chromosomes but it works on smaller ones. Do you know if there's a limit on command line blast? I never heard of it

me neither. Although blast is more suitable for "local alignment". it's good idea to blast the whole chr. You might want try something like MUMmer or Mugsy
