Motif search

[Jung Hoon Ahn]

Hi, there!
I have a question which is not somewhat appropriate in this news group.
When searching motifs or signatures by motif search program, I could see
many amidation, phosphorylation, myristoylation and glycosylation sites.

Can I be sure that this modification sites are all exactly predicted. If
not, how much can I assure it.
In addition, which information and conclusions can I infer from this
modification sites.

I'm waiting for your kind reply.
Thanks in advance.
