| ===== AMT database model ===== | ===== AMT database model ===== | ||
| + | When creating an AMT database (MS Access) from hEIDI, following tables are populated: | ||
| + | |||
| + | * **__Table AMT__**: species of the exported User context | ||
| + | * AMT_ID: index for this AMT tag (generated) | ||
| + | * AMTMonoisotopicMass: peptide calculated mass | ||
| + | * NET: computed from peptide (aligned) retention time using the formula: NET = (retentionTimeSeconds/60 - delayMinutes) / durationMinutes | ||
| + | * PNET: null | ||
| + | * MSMS_Obs_Count: # of child species | ||
| + | * High_Normalized_Score: score (max of child peptides scores) | ||
| + | * High_Discriminant_Score: null | ||
| + | * Sequence: peptide sequence | ||
| + | * msidb_peptide_match_id: peptide_match_id used in MSIdb to create this AMT tag | ||
| + | * **__Table AMT_Proteins__**: proteins on which species match | ||
| + | * Protein_ID: protein identifier | ||
| + | * Protein_name: protein accession | ||
| + | * **__Table AMT_to_Protein_Map__**: map table between AMT & proteins | ||
| + | * **__Table protein_group__**: protein groups in which proteins are gathered | ||
| + | * protein_group_id: protein group identifier | ||
| + | * master_id: master protein identifier | ||
| + | * protein_accession: master protein accession | ||
| + | * score: master protein score | ||
| + | * nb_amt_match: # of peptides that match on master protein | ||
| + | * msidb_pg_id: protein group identifier in MSIdb (protein_group table) | ||
| + | * **__Table protein_to_protein_group_map__**: map table between proteins & protein groups | ||
| + | * protein_id: protein identifier | ||
| + | * protein_group_id: protein group identifier | ||
| + | * nb_amt_match: # of peptides that match on this protein in this protein group | ||
| + | * **__Table identification__**: identifications used in the exported User context | ||
| + | * identification_name: names of identifications included in the exported User context | ||
| + | * **__Table build__**: general information | ||
| + | * date: AMTdb creation date | ||
| + | * msidb_name: MSIdb name | ||
| + | * context_name: name of the exported context | ||
| + | * context_is_saved: is the exported context has been saved to MSIdb ? | ||
| + | * msidb_context_id: context identifier in the MSIdb (look at this field only if the context has been saved to MSIdb) | ||
| + | * duration_minutes: analysis duration in minutes | ||
| + | * delay_minutes: analysis delay in minutes | ||
| - | Below is the AMT database model showing relationships between tables in MS Access.\\ | + | :!: **Notes**: |
| - | Only the three tables ''AMT'', ''AMT_Proteins'' and ''AMT_to_Protein_Map'' are populated. The other tables doesn't contain any records. They will be later populated in the AMT pipeline.\\ | + | * UMCs tables were populated using '[[how_to:includeumcinamtdb|Read UMCs]]' tool until hEIDI 1.12.0.\\ |
| + | * Since hEIDI 1.13.0, [[how_to:importumctomsidb|UMCs result files are included into MSIdb]] (instead of AMTdb) | ||
| - | * The ''AMT'' table contains all the peptides of the context. | ||
| - | * The ''AMT Proteins'' table contains all the proteins of the context. | ||
| - | * The ''AMT to Protein Map'' table links the two previous tables to indicate by which peptides proteins are identified. | ||
