  • TopHat coverage.wig file wish list

    Hi,

    I wanted to add to the list of things to have into account for the next version of TopHat, in case the developers are around.
    I'm using Tophat v1.0.12 and Bowtie v0.11.3
    I noticed that the last line for each chrm in the coverage.wig file ends a position earlier. For example, the last lines for scaffold1 in my coverage.wig file are:

    scaffold1 4408480 4412926 0
    scaffold1 4412926 4413006 1
    scaffold1 4413006 4486297 0
    scaffold1 4486297 4486376 1

    I'm using 80 bp reads as you can see in the 2nd line pasted above (4413006-4412926=80), but the last line of the wig file shows a read of length 79 (4486376-4486297=79) (I've checked the SAM file and this read aligns in all 80 bases) I noticed that this happens on the last read/covered fragment of every chrm.

    Do I get a price for helping make Tophat even a greater software than it'salready? If so, I would like to make one more wish.
    All the chrms end on that last read/fragment aligned as opposed to have a last row with deph of coverage equal to 0 starting from the end of the last read/fragment and finishing at the end of the chrm.
    In the example above scaffold1 is 4553411 nt long. A nice way to finish the chrm would be:
    scaffold1 4486376 4553411 0

    Finishing like this this will make the wig file complete and accurate, and will make it useful for coverage calculations, etc.

    Thanks for developing a great software.

    I check my results. The same case.

      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...

      Strategies for Sequencing Challenging Samples
      by seqadmin


      Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
