  • Problem with running tophat

    I tried to run tophat a lot and I haven't success. I need help please!!!!!
    My reads were sequencing at Solid and this version support this kind of read with the bowtie 1 ( I used Bowtie 1.1.1). I indexed the Phaseolus' genome (.ebtw).

    $ tophat --color --quals -r -p fr-secondstrand ebwt_base_index.fa -o NGR1_NGR2_1_thout genome NFN_run6_Transcriptoma_29102013_bcSample1_F3_NGR1.csfasta NFN_run6_Transcriptoma_29102013_bcSample1_F3_NGR2.csfasta NFN_run6_Transcriptoma_29102013_bcSample1_F3_QV_NGR1.qual NFN_run6_Transcriptoma_29102013_bcSample1_F3_QV_NGR2.qual

    Traceback (most recent call last):
    File "/usr/bin/tophat", line 4107, in <module>
    sys.exit(main())
    File "/usr/bin/tophat", line 3858, in main
    args = params.parse_options(argv)
    File "/usr/bin/tophat", line 1008, in parse_options
    self.read_params.parse_options(opts)
    File "/usr/bin/tophat", line 467, in parse_options
    self.mate_inner_dist = int(value)
    ValueError: invalid literal for int() with base 10: '-p'

    Anyone could help me to solved this?????

    If you use the parameter -r, then you need to specify an integer value for -r, the mate inner distance (distance between the two reads of a pair).

    Otherwise, if you don't specify -r, the tophat manual says the default value is 50.

      Now I don't specify the -r and this message appeared..the files indexes are at directory

      tophat --color --quals fr-secondstran genome.fa -o NGR1_NGR2_1_thout genome NFN_run6_Transcriptoma_29102013_bcSample1_F3_NGR1.csfasta NFN_run6_Transcriptoma_29102013_bcSample1_F3_NGR2.csfasta NFN_run6_Transcriptoma_29102013_bcSample1_F3_QV_NGR1.qual NFN_run6_Transcriptoma_29102013_bcSample1_F3_QV_NGR2.qual

      What's the problem?

        You have not specified the "basename" (ebwt_base_index, if that is the name) of the index files for the genome that you are searching against.

          Hi Luana,

          You are missing the final 'd' from fr-secondstrand, and you are also
          missing the /path/to/ the bowtie index (give only the prefix of the index name).

            Hi Guys,
            I'm trying to fix this script but the problem persist. I put the "d" in the fr-secondstrand, but I didn't understand witch file from index directory I have to use.
            When I indexed the genome I used the fasta file and I had six files .ebwt
            How file index .ebwt I have to use in this script?

            tophat --color --quals fr-secondstrand /bowtie/bowtie-index/ebwt_base -o NGR1_NGR2_1_thout genome NFN_run6_Transcriptoma_29102013_bcSample1_F3_NGR1.csfasta NFN_run6_Transcriptoma_29102013_bcSample1_F3_NGR2.csfasta NFN_run6_Transcriptoma_29102013_bcSample1_F3_QV_NGR1.qual NFN_run6_Transcriptoma_29102013_bcSample1_F3_QV_NGR2.qual

              you use what is know as the 'prefix', the common part of the filename before the .ebwt, so all 6 of your index files should have the same 'prefix'.

              Also, do you have single-end or paired-end reads? If your reads are single-end, then you should have a comma instead of a space between the names of the two read files, and between the names of the 2 quality files.

                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...
