Make a mutation score heatmap GUI

[Tom Goddard]

None of the current mutation score tools (scatter plot, histogram, color structures) give a view of all the different scores. Would be nice to have an interactive heatmap showing all the mutation scores that interacts with associated structures.

[Tom Goddard]

A basic heatmap mutation score GUI is available using command "mutationscores heatmap". There are still many features and command options to be added. Once it is more functional I plan to make opening a mutation score .csv file bring up an initial tool panel with buttons for heatmap, scatter-plot, histogram, structure coloring, and a list of currently open mutation sets.

I added an Options button to the heatmap gui with options to choose the colormap and to show unnormalized mutation scores.

Added options panel controls to choose mutation set, specify score names to include, highlight mutations with structure residues (formerly was in context menu), subtract fit. Three different colormaps are used for normalized, unnormalized, and unnormalized fit subtracted scores.

Made several heatmap improvements:
Added zoom factor (pixels per cell).
Made save image include all of heatmap and axes.
Allowed mouse hover to color structure residues.
Added drag box coloring of associated residues.
Added amino acid order to options panel.
Added option to group heatmap by amino acid or score name on vertical axis.

[Tom Goddard]

Here are features I plan on implementing in the next few days or week.

Show only selected residues in heatmap.
Show heatmap x-axis labels of residue amino acid and number in vertical text.
Save heatmaps in sessions.
Be able to set all heatmap options by command.

Some other possibilities are:

Allow naming heatmaps which will remember all the settings.
Show computed residue scores in heatmap instead of per-mutation scores.
Allow coloring structures based on mutation scores for selected rectangles on heatmap.
