    processing 454 rna-seq data

    OK. I have rna-seq data from 3 mice. I want to align this data to the mouse reference -- either genome, which seems like overkill, or to all the known mRNAs from Acembly -- which I have in FASTA format.

    The data came from 454 as FASTA (.fna) and .qual files.

    I've also obtained the SFF files.

    TopHat didn't seem to like the FASTQ files I generated from the FASTA and .qual files using BioPython's SeqIO functions.

    There's a really big range of read lengths in this data, which also seems to make a lot of the tools (since they were engineered for Illumina GA output) unhappy.

    Thoughts? Advice? I'm on a Mac Pro, but have 64-bit linux and Windows XP running via virtualization.

    Thanks,
    Anand

    Improved Targeted Sequencing: A Comprehensive Guide to Amplicon Sequencing
    by seqadmin



    Amplicon sequencing is a targeted approach that allows researchers to investigate specific regions of the genome. This technique is routinely used in applications such as variant identification, clinical research, and infectious disease surveillance. The amplicon sequencing process begins by designing primers that flank the regions of interest. The DNA sequences are then amplified through PCR (typically multiplex PCR) to produce amplicons complementary to the targets. RNA targets...

    Targeted Sequencing: Choosing Between Hybridization Capture and Amplicon Sequencing
    by seqadmin




    Targeted sequencing is an effective way to sequence and analyze specific genomic regions of interest. This method enables researchers to focus their efforts on their desired targets, as opposed to other methods like whole genome sequencing that involve the sequencing of total DNA. Utilizing targeted sequencing is an attractive option for many researchers because it is often faster, more cost-effective, and only generates applicable data. While there are many approaches...
