I am wondering if I am encountering an unknown XREF limitation?
Given the following AceDB model
?Sequence DNA UNIQUE ?DNA UNIQUE Int
Title UNIQUE ?Text
Matching_genomic_sequence UNIQUE ?Sequence XREF Matching_ESTs
Matching_ESTs ?Sequence XREF Matching_genomic_sequence
Now given the following ace file
Sequence : g1
Sequence : g2
The above acefile is intended to say that the same EST sequence e
matches both Genomic_sequence g1 and g2 (probably because g1 g2 are
homologous seq). However, Then when this data file was loaded into
AceDB, the database only recorded the second information g2 - e but
flushed out the first one g1 - e.
Is this a known XREF limitation? If so, Any suggestions of how to overcome it?
Thanks in advance!
