why i need to use linux?
because bioapps are based on linux.It is a syetem which is free and open to the world and does not contain pictures which will waste resources.And the Command Line code , meeting the need of analysing ,could handle many documents efficiently at the same time. when the dates are high to tens or hunreds G, the windows cannot meet your need,but linux could.
how to log in
1.download and install xshell
2.log in
