DCC uses output from the STAR read mapper to systematically detect back-splice junctions in next-generation sequencing data. DCC applies a series of filters and integrates data across replicate sets to arrive at a precise list of circRNA candidates.

Grouping of samples and replicates #80

Closed EricSHo closed 2 years ago

EricSHo commented 4 years ago

Hi,

My installation is DCC 0.4.8 ubuntu

I have a question about the grouping of samples of replicates.

My data consists of 4 experimental conditions, and 3 replicates per condition.

Should I specify all 4x3=12 Chimeric.out.junction entries in one samplesheet/mate1/mate2? In this case, I run DCC only once.

Or, should I create 4 separate samplesheets/mate1s/mate2s, one for each condition, and each contains 3 replicates? In this case, I need to run DCC 4 times.

Thanks, Eric.

Hi @EricSHo,

generally you can run everything together and later on pull only those circRNAs that are specific for one condition. When you want to use circtest in the next step having a combined table will also make that step easier.

Cheers, Tobias
