[Difx-users] Missing scans when using DiFX 2.6.1

[Adam Deller]

Hi Matt,

Are the scans definitely present in both cases after running vex2difx (that
is, have identical .input, .calc etc files been generated)? If not, the
problem would be at the vex2difx stage, and the missing baselines were
never correlated.  If so, are all the .difx output files generated after
running DiFX and are they the same size? If not, the problem is in
mpifxcorr.  If so, then indeed, the problem is likely with difx2mark4.

Is there any reason why you are using different versions of difx2mark4 and
vex2difx/mpifxcorr/etc?

Cheers,
Adam
