| - | To generate a new AMT database in the MS Access format (.mdf file) from a given User context, follow these steps: | + | :!: **Requirements** \\ |
| - | {{:amtexport_menu.png |Export a context to a new AMT database}} | + | * Context have to be **[[how_to:proteingrouping|grouped]]** previously. You generally apply some filtering during and/or after the protein grouping step to suppress: |
| + | * Reverse proteins | ||
| + | * Species with a sequence < 7 | ||
| + | * Proteins identified by only 1 species with a score < 60 | ||
| + | * **[[how_to:alignretentiontime|Retention time alignment]]** & **[[how_to:recomputeretentiontime|retention time recomputing]]** algorithms may have to be run before creating | ||
| + | * Save your MSIdb | ||

| ===== AMT database model ===== | ===== AMT database model ===== | ||
| + | When creating an AMT database (MS Access) from hEIDI, following tables are populated: | ||
| - | Below is the actual AMT database model showing relationships between tables in MS Access.\\ | + | * **__Table AMT__**: species of the exported User context |
| - | + | * AMT_ID: index for this AMT tag (generated) | |
| - | When exporting an AMT database from hEIDI, only the 5 following tables ''AMT'', ''AMT_Proteins'' and ''AMT_to_Protein_Map'', ''protein_group'', ''protein_to_protein_group_map'' are populated. | + | * AMTMonoisotopicMass: peptide calculated mass |
| - | + | * NET: computed from peptide (aligned) retention time using the formula: NET = (retentionTimeSeconds/60 - delayMinutes) / durationMinutes | |
| - | * **Table AMT** (contains all the peptides of the context) | + | * PNET: null |
| - | * **Table AMT_Proteins** (contains all the proteins of the exported context) | + | * MSMS_Obs_Count: # of child species |
| + | * High_Normalized_Score: score (max of child peptides scores) | ||
| + | * High_Discriminant_Score: null | ||
| + | * Sequence: peptide sequence | ||
| + | * **NEW** :!: **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_ID: protein identifier | ||
