Re Further grouping and analysis is a bit more fuzzy in my mind as yet.
Yes, grouping seems like a very open-ended question. From experience using my tool, here’s a new variation I thing I will at least try out.
Allow the standard notation of sets of bases (S,W, R, … in addition to C, G, U, …) to be used in grouping as well as filtering. That is, in addition to specifying a position to group on (which multiplies by four the potential number of different groups), one could specify a position and a letter. For example 17S in the group by option would split designs into just two groups, S and W (i.e.not S).
OK, I have a very rough example of a secondary structure server running from a Google spreadsheet. The spreadsheet URL is https://docs.google.com/spreadsheet/ccc?key=0AkRBfaX8rvhLdE9TVWdRdWlQLWJxTFY1TmxjbDB1b3c&usp=sharing. I’'ve manually entered five labs, with their target structure. In the spreadsheet, if you click on Tools/Script Editor, you should be able to see the Javascript code for the server. (But I haven’t verified that it is visible to anyone who has access to the spreadsheet itself.)
Thanks for the example. I can see the spreadsheet and run the code, but I cannot see the script. Have sent a request for additional access for my gmail account. Thanks.
