  • Please, examine my fastq file. Help me, one more time!

    I ran - ELAND_standalone.pl with fasta to fastq converted file.

    like this...

    perl ELAND_standalone.pl -if /data/clip/fus/lane1.fa -it fastq -eg /data/Genome/ELAND/mm9/

    but.. I got an error message like this:

    Could not identify index of the following line: EAS41_4_1_200_725_616_963
    Please check your files.


    My fastq file contains.......

    @EAS41_4_1_200_725_616_963
    CGTATGCCGTCTTCTGCTTGTCGTATGCCGTCTTCT
    +
    ::::::::::::::::::::::::::::::::::::
    @EAS41_4_1_200_232_69_883
    ..................................................................................

    I must finish ELAND_standalone program with this file by weekend. (or I will die)

    I'm trying to run this program with another fastq file, but could not identify the first line of files.

    Please, help me~~

    why not try "fq_all2std.pl" in MAQ

      Sejong,

      The format of your read ID tags is incorrect, Eland can not interpret them. The required format looks like this:

      Code:
      @HWI-EAS216:1:2:1:2017#0/1
      
      It represents:
      
      @<machine_id>:<lane>:<tile>:<x_coord>:<y_coord>#<index>/<read_#>
      The underscores ( _ ) should be replaced with colons ( : ) in the. Also add "#0/1" to the end of each name. The #0 indicates that no multiplex indexing was used. the /1 means that this is either that this read is from a single end run or it is read 1 from a paired read run.

      There also seems to be too many numbers in your read names. There should be four numbers following the machine id which identify the lane, tile, x and y coordinates of the read. Your read names have six numbers. Are they from an earlier version of the pipeline?

          Recent Advances in Sequencing Analysis Tools
          by seqadmin


          The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...

          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...
