-How specific values are calculated: ​ 
-  * MonoistopicMass:​ calculated_mass 
-  * NET: (Retention Time/​60)-delay)/​duration (delay & duration are information entered by user, retention time is expected in seconds) 
-  * PNET : null 
-  * MS_MS_Obs_Count:​ # of child species 
-  * sequence: species sequence 
-  * High_Normalized_Score:​ score (max of child species scores) 
-  * High_Discriminant_Score:​ null

-Below is the actual ​AMT database ​model showing relationships between tables in MS Access.\\ +
- +
-When exporting an AMT database ​from hEIDI, ​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

 +  * 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.
