1.Type
the study name in the box provided. (Study name is for your reference, it does
not change the way program works.)
2.Choose
the P value cutoff (choose default value of 0.05 if you are doing the search
for the first search)
3.Click
on the Search button.
The
search time taken is 10 seconds to 30 seconds and might vary depending on the
number of IDs entered and the internet speed. Reduce the number of Ids if
the results page takes more than 2 minute to load.
Biointerpreter
will search your gene identifiers in the comprehensive annotation database. It
will retrieve all the necessary annotation from the database. Then it will sort
out the results in to different category like functions, disease, pathway,
chromosome, etc.
The result will be
categorized in to following categories.
-
Summary report
-
Chromosome
-
Pathway Function
-
Disease
-
Localization
-
Gene Expression
-
Cancer Gene expression
-
Protein domain
-
Protein Ligand
-
Tissue expression
-
Gene Ontology
-
Hot molecules
-
Drug response
Under
each category, there will be subcategory / elements. For example a list of
functions will be displayed under the function category. For each function, the
number of genes supporting the function, and P value will be given.
Biointerpreter counts the number of genes in the query list supporting each
function and will find the significance. A set of significant functions will be
retrieved and displayed. NOTE: Some categories are not available in the demo
version.
P
value:
P
value (Probability value) is the probability of getting the same result with a
random set of gene identifiers. Chi-square test is used to calculate the
P value. Chi-square is a common statistical method used to derive P value
of the (input) observed data and expected data. If the P value is about 0.10,
it means there is a 10% probability that the deviation is only due to chance
and other factors are involved. P value less than 0.05 considered as
significant. The results are sorted by P value in increasing order.
To
View the gene details in tablular format:
Each
category will display the members of the category, number of genes supporting
the member and P value for the member. In the first result page the
following operations can be performed
-
View the pie chart for the selected functions / disease / localization etc.
-
View the details for the selected subcategory / elements in the table view with
AND / OR query.
(Here
we have explained for functions. The same can be implied all the result
categories)
AND
/ OR query for the table view
AND
query – The genes which are associated with all the
selected functions will be displayed.
OR
query- The genes which are associated with any one of
the selected functions will be displayed in the table view.
