If you export as nv from nmr pipe (pipe2xyz -nv) it should be blocked just not sure if nmrview does above 3d but my expectation is that it does

The data looks great but very large (my .ft4 file is ~30 GB). I am running 64-bit CCPNMR version 2.4.2 on a 2014 MacBook Pro running El Capitan (see screenshot below)

I have tried to change the graphics handler from Tk to OpenGL but CCPN crashes (as documented in posts dating as recently as 2012). I have also tried using a linux box with Nvidia GeForce (cuda) video card, 6 GB system memory, and an i7 processor. I see no improvement in performance. In the case of my linux system, I’m again running a 64-bit version of Analysis 2.4.2.
