Test the orthology relationship between two entries. Possible answers are 'not orthologous', '1:1 orthologs', '1:many orthologs' or 'many:1 orthologs'. The two parameters are preferably OMA entry identifiers (e.g. ECOLI1190). Many other IDs are also supported (e.g. Ensembl protein/gene identifiers, SwissProt IDs, etc.) whenever they were annotated in the original databases.

Lists all orthologs for a given entry. To learn more about the exact relationship to the returned entries, use the TestOrthology function. To get more information, specifically the protein sequence and the organism, use the GetEntry function. The argument is preferably an OMA entry identifier (e.g. ECOLI1190). Many other IDs are also supported (e.g. Ensembl protein/gene identifiers, SwissProt IDs, etc.), whenever they were annotated in the original databases.

For any OMA group, this function returns a list IDs of all member proteins.

Given an OMA entry identifier or another ID, this functions lists all possible IDs and cross-references for this entry that were found in the original database. Also returned are the protein sequence, the OMA group and the organism name.

This function provides an easy way to map any sequence to the OMA entries by searching the input protein sequence in the OMA database. A list of all entries that contain this sequence is returned.

This function returns the name of the current data set as well as the number of species and OMA groups in this data set.

Get the list of ID types, which is of the form [[0,"OMA ID"], [1,"SwissProt ID"], ...].

Map a list of IDs (of any type) to a IDs of a specified type. Use the ListIDType command to obtain a list of possible ID types
