*  The network predicts the three secondary structure types using real     *
*  numbers from the output units. The prediction is assigned by choosing   *
*  the maximal unit ("winner takes all").  However, the real numbers       *
*  contain additional information.                                         *
*  E.g. the difference between the maximal and the second largest output   *
*  unit can be used to derive a "reliability index".  This index is given  *
*  for each residue along with the prediction.  The index is scaled to     *
*  have values between 0 (lowest reliability), and 9 (highest).            *

*  Often the relative accessibility is projected onto, e.g., 3 states:     *
*     b  = buried       (here defined as < 9% relative accessibility),     *
*     i  = intermediate ( 9% <= rel. acc. < 36% ),                         *
*     e  = exposed      ( rel. acc. >= 36% ).                              *

*  The network predicts the 10 states for relative accessibility using real*
*  numbers from the output units. The prediction is assigned by choosing   *
*  the maximal unit ("winner takes all").  However, the real numbers       *
*  contain additional information.                                         *
*  E.g. the difference between the maximal and the second largest output   *
*  unit (with the constraint that the second largest output is compiled    *
*  among all units at least 2 positions off the maximal unit) can be used  *
*  to derive a "reliability index".  This index is given for each residue  *
*  along with the prediction.  The index is scaled to have values between  *
*  0 (lowest reliability), and 9 (highest).                                *
*  The accuracies (Q3, corr, asf.) to be expected for residues with values *
*  above a particular value of the index are given below as well as the    *
*  fraction of such residues (%res).:                                      *

GLOBE prediction of globularity


--- 
--- GLOBE: prediction of protein globularity
--- 
--- nexp =   213    (number of predicted exposed residues)
--- nfit =   165    (number of expected exposed residues
--- diff =    48.00 (difference nexp-nfit)
--- =====> your protein appears as compact, as a globular domain
