Function and data introduction

The web server RRBS-Analyser is developed for comprehensive characterizing the methylome in one or multiple samples. It is intended to identify and annotate the methylation sites and inspect the differentially methylated regions.
Only FASTQ, SAM or MC format files are allowed in RRBS-Analyser.The introductions are depicted in "Input file introduction". If you choose FASTQ format file to upload, only one sample is allowed, for SAM and MC formats, both simple and multiple samples are allowed.

Input format

Upload data

Firstly: using ftp tools to upload file.
If so, please select ftp; Username: rrbsanalyser   Password: rb18fa6dan!

Secondly: After upload successfully, input your file names, for multiple samples, each file name separated by comma (,)
                        such as Sample1.sam.tar.gz,Sample2.sam.tar.gz
If users want test RRBS-Analyser with default data, only need to touch the "submit" button.

Due to the data set needed to analysis is too large, please wait patiently.
