Dear All I have an experiment which is an hncoca and I have set the experiment type H [N[co[CA]]]. However it only seems to have one ExpTransfer between 1H and 13C there is no H N ExpTransfer 1. I have checked all the ExpDimRefs are present.... 2. if I change the type of the experiment to an HNCO I get two ExpTransfers again 3. if I add a new spectrum and set the type to hncoca again I only get one ExpTransfer 4. not the CA shift ranges are correct and match my hnca which has got two ExpTransfers help!! regards gary -- ------------------------------------------------------------------- Dr Gary Thompson Astbury Centre for Structural Molecular Biology, University of Leeds, Astbury Building, Leeds, LS2 9JT, West-Yorkshire, UK Tel. +44-113-3433024 email: [log in to unmask] Fax +44-113-2331407 -------------------------------------------------------------------
