LSC is a long read error correction tool.
It offers fast correction with high sensitivity
and good accuracy.


Latest News: LSC 0.3 -- Support BWA, Bowtie2, RazerS3, much faster and more accurate ... read more
.Getting Started
These simple steps will help you integrate LSC into your transcriptomics analysis pipeline.

•Read the LSC_requirements for running LSC.
•Download and set-up the LSC package
•Follow the tutorial to see how LSC works on some example data.
•Check the manual if anything is unclear.
•You're ready, Happy LSCing!

08-07-2013: Big changes in LSC 0.3
In LSC 0.3, we have a few updates. They are very IMPORTANT updates, new features and small fixes

Very IMPORTANT updates:

•Support for Bowtie2 and RazerS3 as initial aligners. Now, BWA, Bowtie2, RazerS3 and Novoalign work in LSC. Please see the comparison details of aligners in the "Short read - Long read aligner#manual".
•Added SR length coverage percentage on LR (SR-covered length/full length of corrected LR) to corrected_LR output file. Here is an example, where the last number 0.82 is the SR length coverage percentage on LR:
>m111006_202713_42141_c100202382555500000315044810141104_s1_p0/18941/365_1361|0.82
•Added support for three modes for step-wise runs:
mode 0: end-to-end
mode 1: generating LR_SR.map file
mode 2: correction step
•Generating FASTQ output format based on correction probability given short read coverage. Please refer to LSC paper and manual page for more details. You can select well-corrected reads for downstream analyses by using the quality in FASTQ output or SR length coverage percentage above. Please the the filtering in the "Output#manual".
New features

•Used the python path in the cfg file instead of default user/bin path
•Added option (-clean_up) to remove intermediate files or not (Note: important/useful ones will still be there in temp folder)
•Support for input fastq format for LR (long reads) and/or SR (short reads)
•Updated default BWA and novoalign commands options
•Printing out original LR names in the output file
•Support for printing out version number using -v/-version option
Small bug fixed

•Fixed in removing XZ pattern printed out at the end of some uncorrected_LR sequences
•Fixed samParser bug (which was ignoring some valid alignments in BWA output)
