    I was trying to do a very similar thing a few years back, and initially I tried mapping my ESTs to the genomic data use est2genome and then trying to interpret the gene structure. In short, I ended up using Scipio (not the web-based version) and it worked very well. Just pick a closely related species' genome if your species of interest has not been sequenced yet.
    Hi,I am using scipio now,according to the manual, I need to use perl script scipiogff2gff.pl to convert the file format to .gff, but I can't find it...
    can you help me?
    Many thanks

  • Automating intron discovery in EST-derived gene models

    So, yes, I have a large number of gene models that are derived from EST data. That is, the coding sequence is correct but any introns will be missing. I also have a bunch of 454 genomic sequence (enriched for the particular genes) which will enable me to find the introns.

    Obviously I can just map the raw 454 genomic sequence to the gene models to find where introns are, and I have done this. However I don't really want to do it manually for each gene model.

    I was thinking to derive some sort of consensus sequence from the genomic sequence mapped onto the (reference sequence) gene model, with a large tolerance for introducing gaps in the gene model (which would be introns). At a bit of a loss as to how to do this. Any suggestions on how to automate this process?

    Best Practices for Single-Cell Sequencing Analysis
    by seqadmin



    While isolating and preparing single cells for sequencing was historically the bottleneck, recent technological advancements have shifted the challenge to data analysis. This highlights the rapidly evolving nature of single-cell sequencing. The inherent complexity of single-cell analysis has intensified with the surge in data volume and the incorporation of diverse and more complex datasets. This article explores the challenges in analysis, examines common pitfalls, offers...
