Spectral data corresponding to the ID string xxx does not exist -- March 25, 2016 - 00:48

Hello,


I am new to Relax and have been trying to setup my R1 relaxation analysis 
using the Relax GUI (4.0.1). My input files come from NMRView. I opened all 
the files under "The file name(s)" menu - they all have .xpk extensions (an 
example is R1-methyl_hRGS4_20C_pH7_Mar2016_0ms.xpk). I then provided a set of 
spectrum ID string names that matched the filenames (minus the .xpk extension 
- an example is R1-methyl_hRGS4_20C_pH7_Mar2016_0ms). When I try to continue 
from that window I get the following error:


RelaxError: Spectral data corresponding to the ID string

Please help!
