Hi David,

I'm not sure what you mean by x,y data.  Do you have 1D signals / images / videos / something else?

From your description, I presume one of the dimensions is time... linescan images obtained using confocal microscopy are used for imaging brief calcium events and often denoted x,t (one spatial and one time dimension), whereas full frame videos can be denoted x,y,t (two spatial dimensions and one time).

There has been some software described in the literature for detecting and analysing brief calcium events (e.g. calcium sparks) in both of these types of image, although I don't know if they would be appropriate for your data.  If you let me know more about the sort of data you have, maybe in an email, I might be able to be more use.

Regards,

Pete
