  • Preparing text files with counts for DESeq2

    All, we have been using DESeq for about a year now, and would like to compare our results to DESeq2.

    We have been using raw count files in text format. What are the commands to convert a text files (.csv) to a format readable by DESeq2? This may be obvious to experienced R users, but has us at a complete loss.

    Our files contain gene names in column 1 and sample names (biological replicates, 4 for each experimental condition) in row 1. Gene names are not duplicated and counts are in integers.

    The formats are (or at least can be) the same for both DESeq and DESeq2. Just use read.csv() as you would for any other CSV file.

      "DESeqDatasetFromMatrix" is the function you want to use instead of "newCountDataset"

        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...
