Hello,  I have some x,y data of pulses which have a sharp rise and slow decay from some experiments on the release of calcium ions inside cells.  I need to characterise the pulses and it would seem sensible to go for the basic parameters of rise time deacya half-time and maybe exponential curve fitting.  I'm not a programmer, so I wondered if anyone knows of a program that already written to do this please?  Thank you, David (Leicester UK)
