  • MapSplice V1.15.2 error

    Hi all

    Im using Mapsplice with pair reads. I got the error message:


    error: open entended file error

    [FAILED]

    Error: check reads format failed


    Any idea to solve this error??

    Regards

    It's probably "error: open extended file error", not "error: open entended file error"

    Any previous output? , there's usually a complete narrative which looks like this example ...

    [Thu Jun 21 11:17:06 2012] Checking for chromosomes files or directory
    [Thu Jun 21 11:17:07 2012] Checking for chromosomes files or directory passed
    [Thu Jun 21 11:17:07 2012] Checking for Bowtie index files
    [Thu Jun 21 11:17:07 2012] check reads format
    [Thu Jun 21 11:19:23 2012] merge paired end reads remove short
    [Thu Jun 21 11:27:15 2012] Mapping reads against bowtie_index_basename with Bowtie

    What is the name of the last output in the logs directory ???


    The program bin/mapsplice_segments.py contains the "check reads format failed" strings at line 4946 of 7830 ...
    Code:
        if DEBUG == 1:
            print >> sys.stderr, "[%s] check reads format" % dividereads_cmd
        #print >> sys.stderr, "[%s] divide reads" % dividereads_cmd
        try:
            retcode = subprocess.call(dividereads_cmd, stdout=mapsplice_log)
    
            if retcode > 0:
                print >> sys.stderr, fail_str, "Error: check reads format failed"
                exit(1)
    So it's dividereads_cmd is failing.

    It looks like there's a nice debug command in the "if DEBUG == 1" clause on line 4939.

    Try turning on DEBUG = 1 on line 120 of the python source file "bin/mapsplice_segments.py", then re-run it. That should give you a better hint.

    Remember to set the path to point to the mapsplice "bin" directory in addition to your regular path.

      Hi

      Problem solved. I forgot to put the path of the read_end2:

      I put "path/read_end1, read_end2" but the correct is "path/read_end1, path/read_end2".

      Many thanks,

      P

        Essential Discoveries and Tools in Epitranscriptomics
        by seqadmin


        The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist on Modified Bases...

        Current Approaches to Protein Sequencing
        by seqadmin


        Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...
