I have been able to draw a baseline from Analysis> Peaks and Baselines> Peak Analyser> Open Dialog..> GOAL= Find Peaks> BASELINE MODE= User Defined etc but I can't get it to measure peaks or draw the peaks if they are not there, i know this is probably quite an unusual requests. Please can someone tell me if this is possible? Origin Ver. and Service Release (Select Help-->About Origin): Operating System: OriginPro 8 [/quote]   Check here to include your profile signature.
