Re: [modeller_usage] modeling mutations



Hi Miguel,

First, congratulations for using bioinformatic...
With your script, you will generate 5 models. I think it not enough.
Basically, modeler generates models and attributes for each one what we
call an 'objectiv function', which corresponds approxymately to the energy
of the model (constraints included). So, the more models you will
generate, the more you will have a chance to choose the model with a very
low energy.
Moreover, it seems that the mutation you want to test is in a
loop. So, under modeller, you can use another function, which uses a
better scoring function for modelling (you find it in last pages of the 
documentation).

I hope this will help you.

Good luck,
Mickael Krzeminski
