Displaying tables with BR, TR or perturbation id

[jcasadogp]

When the user selects the createInfoFile or plot options, the program will display (depending on the option) tables with existing studies, biological replicates, perturbations and/or technical replicates. The displayed messages should be revised. For example:

There are no perturbations with biological replicate id 101: => check for technical replicates

This message is OK if then the user is going to select a technical replicate ID (e.g., plotting option 1), bit, if plotting option is 2 (plot one set of technical replicates), the program should not go further, and, hence, that message should not have been displayed.
