Batch: Multi-threaded Probabilistic Base Calling
In Rolexa: Statistical analysis of Solexa sequencing data

Description Usage Arguments Details Author(s) References See Also Examples

Performs multi-threaded base calling on a collection of intensity files generated by the Solexa image analysis software

ForkBatch(run=Rolexa.env,path,outpath="./",prefix="rs_",nthreads=3,nfiles=2,lane=1,tiles=1:100,...)
## S4 method for signature 'RolexaRun'
OneBatch(run,path,lane,tiles,outpath,prefix)
OneBatch(run,...)

`run`	a RolexaRun object defining the run parameters
`path`	a SolexaPath object defining providing the input paths
`outpath`	the path to the output directory
`prefix`	output file prefix, see `SaveResults`
`nthreads`	number of threads to use
`nfiles`	number of input files to concatenate in one batch
`lane`	the lane number to analyze
`tiles`	a subset of tiles to read
`...`	further arguments passed to the RolexaRun constructor

The function ForkBatch runs through the list of input files, concatenates them by batches of nfiles, then calls OneBatch in each of the nthreads threads until all batches have been processed. Each batch results are passed to FilterResults and saved in an output file inside outpath.
