Have you copied the peak assignments across? If so then when you export you should be able to match up the peaks fairly easily (and so compare intensities).

For example, would I be ok to pull out the intensities of all the peaks onto a spreadsheet and do it manually – or is there a better way of doing this within CCPN? > > Thank you for your help! > Best wishes, > James
