Hi :) I'm completely new to galaxy so sorry for bothering you with maybe silly questions. I'd like to create a web service based on galaxy to process time series using clustering algorithms in order to semplify complex data into representative clusters. Our tools are python scripts that take as input a matrix containing time series, each row is a timeseries and each column a point of the time series. Usually we use CSV for files. We have files like: id|01/01/2009|02/01/2009|03/01/2009|04/01/2009 id1|5|3|3.21|8 id2|2|1|9.1|2 id3|5.2|2.43|1|4 Where the first row is the header and the others row the the id of each time series and then the time series itself. Have I to add a new datatype?Or can i use tabular? outputs and inputs are always saved on file right?and at any process are parsed again? I need then the plot of the time series and the clusters how can i do it? Thank you -- f. "E' in un giorno di pioggia che ti ho conosciuta e il vento dell'ovest rideva gentile..."
