Due to an error in formatting of P27, hydrogen atoms in these models
were not considered as such and therefore included in the
determination of clashes. This has now been corrected. Although
proper inclusion of these predictions would lower the clash threshold
we will keep the previously calculated value of 80. Therefore *only*
P27 is affected by this correction.

Some predictions were disqualified on the basis of too many clashes,
where in fact these clashes involved hydrogen atoms, that should not
be taken into account in the determination of clashes. Due to an
error in formatting, these hydrogen atoms were not recognized as such.
These predictions have been re-assessed:
| model | fnat | L_rms | I_rms | classification |
| T41_P27.M07 | 0.6964 | 6.8575 | 1.7340 | medium |
| T41_P27.M08 | 0.5714 | 10.7231 | 2.4827 | acceptable |
| T41_P27.M10 | 0.5536 | 10.8460 | 2.6221 | acceptable |
| T41_P27.M04 | 0.4107 | 10.8551 | 2.9214 | acceptable |
On a sidenote, the correction would lower the clash threshold from 80
clashes to 63. However, we will maintain the determined clash
threshold of 80 for predictor and scorer-submitted models, so
acceptable models with a number of clashes more than 63 but less than
80 are still acceptable:
| model | clashes | classification |
| T41_P13.M02 | 65 | acceptable |
| T41_P13.M03 | 73 | acceptable |
| T41_P41.M07 | 70 | acceptable |
| T41_S03.M04 | 74 | medium |
