How to generate consensus sequence for all refs (Read 33867 times)

Hi,

I have been trying to use samtools to create consensus sequences. However, it seems that conseqs.fastq (see command below) is missing consensus sequences for most reference sequences.

--- samtools command ---
samtools mpileup -uf ref.fa sorted.bam | bcftools view -cg - | /usr/share/samtools/vcfutils.pl vcf2fq > conseqs.fastq
----

In IGV, I can create consensus sequence for all references (one by one). I would like to create the consensus sequences with a command line tool.

I asked this question at seqanswers forum and got an answer that creating the consensus sequences is possible with UGENE command line.

Can I have an example of an UGENE command that can be used to build consensus sequences from ref.fasta and sorted.bam files?

Thanks

Hello,

In the current UGENE version 1.14.1 you can do the task only partially:

1) You can find out variants by a reference sequence and an assembly. It is the same as command:
Code:
samtools mpileup –uf <input_reference> <input_bam> | bcftools view –vg – | vcfutils.pl varFilter –D 100

For details, see: Call Variants with SAMtools

2) You can find out a consensus sequence from an assembly.
For details, see: Extract Consensus from Assembly

Unfortunately, it is not possible to get a new sequence from a reference + variations combination. We will add this feature into the next major UGENE release 1.15. Here is the link to the corresponding request in our issue-tracking system: UGENE-3588
Note that any workflow in UGENE can also be run from the command line.

Is the input still the same to do this in version 1.15 because I input that code and nothing happened.

What do you mean? The workflow in UGENE is still the same. Do you mean the original SAMtools command line tool?

I'm still using version 1.14.1 because I love this version so much that I never updated it. But I can't get a new sequence from a reference and variations combination in this version. What do you suggest? Should I upgrade to the latest version 1.29.0? Or is it possible to do so in any version above 1.14.1? If yes, where can I download it from?

Thank you for the feedback, Priscilla!

Unfortunately, this feature is not yet available in UGENE 1.29.0 as well. Instead, you might use, for example, FastaAlternateReferenceMaker from GATK (in the command line).

We'll take into account your request and add this feature in one of the nearest UGENE versions.

Are you using the latest version (1.31.1)? Because it is working fine for me.
