See How Cufflinks Workshow_it_works/index.html#) for more details. Providing Cufflinks with the multifasta file your reads were mapped to via this option instructs it to run our bias detection and correction algorithm which can significantly improve accuracy of transcript abundance estimates. Using this mode is generally recommended in Cuffdiff to reduce certain types of bias caused by differential amounts of ribosomal reads which can create the impression of falsely differentially expressed genes. With this option, Cufflinks counts only those fragments compatible with some reference transcript towards the number of mapped fragments used in the FPKM denominator. With this option, Cufflinks counts all fragments, including those not compatible with any reference transcript, towards the number of mapped fragments used in the FPKM denominator. Samples should be provided in increasing time order at the command line (e.g first time point SAM, second timepoint SAM, etc.) Instructs Cuffdiff to analyze the provided samples as a time series, rather than testing for differences between all pairs of samples. Specify a label for each sample, which will be included in various output files produced by Cuffdiff. Sets the name of the directory in which Cuffdiff will write all of its output. If more than two are provided, Cuffdiff tests for differential expression and regulation between all pairs of samples. ]Ī transcript annotation file produced by cufflinks, cuffcompare, or other source.Ī SAM file of aligned RNA-Seq reads.
