I believe I've seen this one before. Athena cuts all of the groups to the group with the shortest range.
The reason for that is that when you export using the "Save marked groups to a file" option, you are asking Athena to write several groups to a common x-axis. That is, the file will contain the energy (in the case of mu(E) or norm(E)) in the first column, followed by columns containing the data. In order to do that, Athena interpolates all data onto the energy grid of the first group. To avoid interpolation problems, Athena first computes the largest common range in energy of the marked groups. As a result, some groups might be truncated. As Jeremy suggests -- this is a feature, not a bug ;-) B -- Bruce Ravel ------------------------------------ bravel@bnl.gov National Institute of Standards and Technology Synchrotron Methods Group at NSLS --- Beamlines U7A, X24A, X23A2 Building 535A Upton NY, 11973 My homepage: http://xafs.org/BruceRavel EXAFS software: http://cars9.uchicago.edu/~ravel/software/exafs/
