IHM Meeting Summary Apr 12, 2017

Attended by BW, TG and BV

The discussion was mainly focused on the issues on Github.

1. Issue 30: The scale is already provided in pixel_size_width and pixel_size_height fields in the ihm_2dem_class_average_restraint table. So only rotation and translation need to be provided using the current ihm_2dem_class_average_fitting table.

2. Issue 32: BV will create a separate category in the dictionary to group input datasets. The grouping is currently only required by ihm_modeling_protocol category, but may be required in other categories in the future. Separating the grouping of input datasets will keep the ihm_dataset_list table clean, avoiding any repetitions.

3. Issue 31: The issue has been re-opened due to multiple reasons. Removal of duplicate entries in the ihm_starting_model_details table in the nup84.cif example causes loss of information regarding which segment in the starting model comes from which template. The fix is as follows:

   • Add ordinal_id field to ihm_starting_comparative_models
   • Add starting_model_seq_begin and starting_model_seq_end fields to ihm_starting_comparative_models
   • ihm_starting_model_details.starting_model_id and ihm_starting_model_details.ordinal_id are now redundant. BV will analyze downstream dependencies and remove one of the two fields.

4. Issue 8: In a higher level documentation, describe clearly (with examples) the requirements and organization of starting models, input datasets and multi-scale model representation.
