Tool:versions of Software used in mutmap

Question

[Chenglin]

Hi all,

I am going to use MutMAap to identify genomic regions which harbors mutations causing changes in agronomically related traits in rice. I need to install the following programs as recommended in the protocol:

1. Perl (v5.8.8)
2. R (version 2.15.0)
3. BWA (version 0.5.9-r16)
4. SAMtools (0.1.8 or before)
5. FASTX-Toolkit (http://hannonlab.cshl.edu/fastx_toolkit/download.html)

I found these programs have already been installed in our HPC server, but in higher versions. My question is, do I need to install exact versions of the programs as recommend in the protocol, or I can used the higher versions instead? I am new in bioinformatics, please help me? Thanks!
