LocPred

Comparison prediction - structural model


       One of the last implementation of LocPred is the comparison of a prediction and a 3D structural model.

1. Comparison step 1

compar

The first step is to give the 3D structure in terms of Protein Blocks. For this purpose, you can use my PDB reader (coded in C), please see http://www.ebgm.jussieu.fr/~debrevern/DOWN/LECT).

It can be used too to compare the results of the different prediction strategies.

2. Comparison step 2

Graphical results
The results is a two part histogram : (top) the comparison and (bottom) the Neq values.

For every residues is given in pink the probability of the assigned (3D structure) PB and in white the more probable PBs (prediction). For this example, from residue 3 to 14, we have a complete correspondence between predicted and seen PB. Then from positions 15 to 17, a divergence is observed and corresponds to a "predicted" longer helix. Positions 20 is interesting as corresponding to an assigned PB c and in the prediction it is a PB b. In fact, this two PB are really close. So these fragments look quite good.
