The results page displays a heatmap of the specified genes across the selected experiments.
Each row is a gene; each column is an experimental condition;
columns are grouped by experiment. Placing your mouse over an
label or column number displays a
You can remove a gene by clicking on the red X next to the gene symbol.
You can add a gene by entering an identifier in the "Add Gene" box below the
heatmap. See below for more options.
The heatmap display shows a heatmap of the genes selected. If the Profile
Plot was generated with the "Average" probe values selected, then this is an
average of all probes for this gene (which may be from 0-n). If the Profile
Plot was generated with the "Top Probes" then this shows an amalgamation of the
results that have the smallest pvalue for that array (ie: best possible
The 'Average' or 'Top Probes' selection does not affect any results in the "All
Probes" or "P-values view" tabs.
At the top of the main heatmap display you'll see four additional tabs.
The "Data view" tab shows numeric values for each cell of the heatmap.
The "All Probes view" shows the probe values for the genes that were selected. If a
gene has 'no data' shown in the main heatmap display then no probes will show
for that gene in the "All Probes view".
The "P-values view" shows the P-values for all probes in the "All Probes
The "Gaggle/DataMatrix Viewer" is an advanced feature described in a
separate help document
A profile plot appears below the heatmap.
A tool panel appears below the profile plot. There are four tabs:
Filtering, Clustering, Co-Expression, and Download Data.
Filtering. Use this tab to add or remove genes, experiments, and
Clustering. Use this tab to cluster and redisplay the data. The only
option for genes is hierarchical clustering. Columns can be clustered
hierarchically or based on various annotations (eg, by organism or tissue).
Co-Expression. Use this tab to add genes to the display whose expression
data is similar to a gene already being displayed.
Download Data. This tab has options to download the data being displayed or
the entire dataset.
You can save the displayed genes by clicking the "save list to My PDDB" link
at the top of the page. You can use the genes in another PDDB program by
clicking the "send list to tool" link at the top of the page. Clicking on one of
the tools will cause a new page to be loaded with the gene list already included
in the "Select a PDDB List".
