            As described in overview section of singularity build documentation

            build can produce containers in two different formats that can be specified as follows.

            • compressed read-only Singularity Image File (SIF) format suitable for production (default)
            • writable (ch)root directory called a sandbox for interactive development (--sandbox option)

            Adding --sandbox should make the system files writable which should resolve your issue.

            Ideally, I'd suggest adding any apt-get install commands to the %post section in your recipe file.

            Basically this would be the pipeline:

            2. Script loops through every file that has the format ".fastq" and applies specific transformation
            3. Script saves new output in ".fasta" format

            QUESTION

            I have a fasta file with millions of sequences. I want to only extract those that's names match within a .txt file, how can I go about doing this?
            Asked 2022-Mar-08 at 11:29

            I have been sorting through a ~1.5m read fasta file ('V1_6D_contigs_5kbp.fa') to determine which of the reads are likely to be 'viral' in origin. The reads in this file are denoted as Vx_Cz - where x is 1-6, depending on which trial group it came from, and z is the contig number/name from 1-~1.5m. e.g V1_C10810 or V3_C587937...

            Through varying bioinformatic pipelines I have produced a .txt file with a list (2699 long) of the contig names that are predicted (<0.05) to be viral. I now need to use this list of predicted contigs to extract and produce a new fasta file that contains only these contigs.

            The theoretical idea behind my code is that it opens the .txt file (names of each significant contig) and the original fasta file, goes through each line of the .txt file and sets the line (contig name) as a variable. It should then loop through the original fasta file which contains all the sequence information and if the contig name matches the record.id (contig name from original file) it should then export the full record information to a new file.

            I think I am close, but my current iterations seems to run only one or the the other loop as I expect them to.

            Please see the code below. I have added notes below to what runs wrong with each program I have tried.

            I don't have your files so I cannot test the actual performance gain you'll get, but here are some things that stick out as slow to me:

            • the line records=list(SeqIO.parse('DNA_library', 'fasta')) converts the records into a list of records, which may sound inoffensive but becomes costly if you have millions of records. According to the docs, SeqIO.parse(...) returns an iterator so you can simply iterate over it directly.
            • Use a set instead of a list when keeping track of seen records. When performing membership checking using in, lists must iterate through every element while sets perform the operation in constant time (more info here).

            Asked 2022-Jan-01 at 10:04

            I am working with amino acid sequences using the Biopython parser, but regardless of data format (the format is fasta, that is, you can imagine them as strings of letters as follows preceded by the id), my problem is that I have a huge amount of data and despite having tried to parallelize with joblib the estimate of the hours it would take me to run this simple code is 400.

            Basically I have a file that contains a series of ids that I have to remove (ids_to_drop) from the original dataset (original_dataset), to create a new file (new_dataset) that contains all the ids contained in the original dataset without the ids_to_drop.

            I've tried them all but I don't know how else to do it and I'm stuck right now. Thanks so much!

            This looks like a simple file filter operation. Turn the ids to remove into a set one time, and then just read/filter/write the original dataset. Sets are optimized for fast lookup. This operation will be I/O bound and would not benefit from parallelization.
