Protein secondary structure prediction in LOMETS

Hi.

I have a question about Protein secondary structure prediction by PSI-PRED in LOMETS.
Because of very short sequence (8 aa length) predicted, it was not allowed to submit to secondary structure prediction servers.
However, I could submit short peptide to LOMETS online and predict structure.(http://zhanglab.ccmb.med.umich.edu/LOMETS/output/S43870/)
What i want to know is difference of secondary structure prediction between LOMETS and the others.
