[meltsim] difference plot in meltsim?

Hi Jeff,

With the difference plot i mean that the differences in melting curve  
shape, who can be further analyzed by subtracting the curves from a  
reference curve. This helps cluster samples automatically into groups  
that have similar melting curves, so something else then the derivate  
profile, pos map and pos profile.

and i think i made a fault before by presumig i could do it with the  
log data from meltsim because that are the derivate profile data.

i'll send you a file about the HRM tool (light-cycler)we use in the  
lab, that way i can make myself totally clear.

so i wondered if it is possible to simulate these difference plots  
with some software...

kind regards,
