Using cpanm to install Perl modules

CPANM is very smart tools for easy installing of perl modules. 

Here is the weblink where you can download cpanm:
http://search.cpan.org/~miyagawa/App-cpanminus-1.7001/bin/cpanm

After finding cpanm, I always use it to install perl modules. To me, the most interesting functions is that cpanm can handle module dependencies.

Here is an example of using cpanm to install perl module: Venn::Chart

 

-bash-4.1$ cpanm Venn::Chart

P and q values in RNA Seq

The q-value is an adjusted p-value, taking in to account the false discovery rate (FDR). Applying a FDR becomes necessary when we're measuring thousands of variables (e.g. gene expression levels) from a small sample set (e.g. a couple of individuals). A p-value of 0.05 implies that we are willing to accept that 5% of all tests will be false positives. An FDR-adjusted p-value (aka a q-value) of 0.05 implies that we are willing to accept that 5% of the tests found to be statistically significant (e.g. by p-value) will be false positives. Such an adjustment is necessary when we're making multiple tests on the same sample. See, for example, http://www.totallab.com/products/samespots/support/faq/pq-values.aspx. -HomeBrew What are p-values? The object of differential 2D expression analysis is to find those spots which show expression difference between groups, thereby signifying that they may be involved in some biological process of interest to the researcher. Due to chance, the...
