The OLS Dialog is an easy and straightforward way of interacting
with the Ontology Lookup Service (OLS). More information about the
OLS can be found here.
More details about the OLS Dialog can be found at the project web page:
http://ols-dialog.googlecode.com.
There are five ways of searching the OLS using the OLS Dialog:
For all search types the ontology to search in is selected at the top. However, for PSI-MOD Mass Search the ontology is always set to PSI-MOD has the PSI-MOD Mass Search is created with this specific ontology in mind.
Term Name Search simply finds all term names that (partially) match the insert
search term. Insert the first letters of the term to locate
in the search field. Note that the search is in "real time". Meaning that a new
search is started (and the result list updated) for every character
typed. The number behind the search field is the number of currently
matching terms.
Note that in some cases a complete search is not performed until at least four
characters have been inserted. If the wanted term is not found, make sure
that at least four characters have been inserted.
The search results are listed in the table in the middle, and
clicking a term displays additional information about the selected term
in the "Term Details" section below.
When the wanted term has been found, select the term in the table
and click the "Use Selected Term" button at the bottom of the frame.
(Or you can double click on the selected term.)
Term ID Search allows you the locate a given term and its details by
inserting the term id, e.g., MOD:00425 or GO:0000269.
The results are displayed and selected in the same way as for results
from a Term Name Search.
PSI-MOD Mass Search allows you to search the PSI-MOD ontology for specific
modifications using the mass of the modification. There are four
different mass types: DiffAvg and DiffMono corresponding to the
average and mono mass of the mass change the modifications results
in, and MassAvg and MassMono corresponding to the mass of the
modified residue.
Insert the mass, the mass accuracy and the mass type and click on
"Search" to perform the search. The results are displayed and selected
in the same way as for results from a Term Name Search.
Browse Ontology makes it possible to find the wanted term by
browsing the selected ontology. The ontology is displayed using
a tree structure where the relationships between the terms are
highlighted. When selecting a term in the tree, details about
the selected term is displayed in the "Term Details" section.
The results are selected and used in the same way as for results
from a Term Name Search.
In addition to the four general search options, it is also possible to view the term hierarcy of a selected term. When a term is selected simply click the View Term Hierarcy link on top and to the right of the selected terms definition text area. This will display the selected terms term hierarcy as a directed acyclic graph.
