I would like to know if there is a way in which we can merge the
expression data from two different sources onto the same MAPP. For
example, suppose that I have some expression data derived from qPCR
imported onto a MAPP (following a certain predefined criterion) and
then I want to add expression information from another source method
(for example, an ELISA, which therefore would follow a different
criterion), but I want to see all the genes (or gene products) that
are differentially expressed on the same MAPP.
One way in which I thought this possible would be to construct the
input .gex table including both types of information, but once again,
since the two methodologies used are not the same, the criteria to
apply to both types of expression information wouldn't be the same, so
I can't do that (unless I convert one to the other in some way).

Again, thanks for your help!

Hi Susana,

It is possible to visualize different data types simultaneously in
GenMAPP, provided that the data can be combined into one spreadsheet.
This is possible if the two data sets are annotated with the same
primary ID.

We have a tutorial describing how to combine different data sets into
one: http://www.genmapp.org/help_v2/CombiningDatatypes.htm

The two data sets in the example have different types of measurements
in the input data and the criterion used for each data is different as
well. So depending on how your two data sets are annotated (which
primary ID is used), it shouldn't be a problem to merge the data sets
in a similar way.

If you have additional questions, please contact
gen...@gladstone.ucsf.edu directly.

Regards,

Kristina

Thank you, Kristina! I will try this!
