-  Select ''​MS Identifications > Context > Export > Create AMT database''​ from the main menu bar. +    Species with sequence < 7

-When exporting ​an AMT database from hEIDI, ​tables are populated:  ​+When creating ​an AMT database ​(MS Access) ​from hEIDI, ​following ​tables are populated:  ​
  
   * **__Table AMT__**: species of the exported User context   * **__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
 +    * **NEW** :!: **msidb_peptide_match_id**:​ peptide_match_id used in MSIdb to create this AMT tag
   * **__Table AMT_Proteins__**:​ proteins on which species match   * **__Table AMT_Proteins__**:​ proteins on which species match
     * Protein_ID: protein identifier     * Protein_ID: protein identifier
Line 45: Line 62:
     * context_is_saved:​ is the exported context has been saved to MSIdb ?     * 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)     * msidb_context_id:​ context identifier in the MSIdb (look at this field only if the context has been saved to MSIdb)
 +    * **NEW** :!: **duration_minutes**:​ analysis duration in minutes

 +:!: **Notes**: ​
 +  * 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)
  
-UMCs tables are populated when using '​[[how_to:​includeumcinamtdb|Read UMCs]]'​ tool.
