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:

T41_P27.M07 0.6964 6.8575 1.7340 medium

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:
