06.07.2017:  This annotation update is a significant improvement made possible by the upgrade of 
genome sequence V5.2 to V7.0.  As a result of moving from a very fragmented assembly to a very 
contiguous assembly and comparing the results of direct annotation-transfer (using RATT with pacbio 
setting) and gene finding (using Augustus based on RNAseq evidence), many previously incomplete or 
absent gene models are now correctly resolved and many spurious gene models have been deleted.  
In general, Augustus has been observed to have produced excellent gene models with good annotation 
of UTRs which was previously lacking in V5.2.  We have been careful to preserve the original gene 
IDs as "Previous Systematic IDs (PSID)" where genes have been merged/split or newly created. Where 
a 1:1 correspondence exists between RATT transferred and Augustus genes, the original Smp ID has 
been preserved.  In the new annotation, novel genes or merged/split genes have been named with 
an "Smp_3" prefix (eg Smp_300010).
