matching dark frames with linux - by: rkonrad

Sorry that this may be off topic for the forum - but since it's a mainly linux body, I thought I'd ask it.....

I'm trying to find a programme that will accurately match the temperature of my dark and light frames. I use DSS under wine with success. However, the windows, "Darkmaster" which does just this, will not work under wine. Does anyone know of a similar programme for linux?

Thanks!
