xfer-from not picking up table names

[IanHeywood]

Trying to load and apply (with interpolation) a set of G and dE solutions derived using the on-the-fly rebinning. Solutions look sane, but:

 - 21:46:52 - gain_machine       [0.1/0.2 2.8/2.8 0.7Gb] G solutions will be initialized from 1529209968_sdp_l0_1284.full_pol_fg_wtspec_47Tuc_1k.ms/chain-field_0-ddid_None.parmdb
 - 21:46:52 - main               [0.1/0.2 2.8/2.8 0.7Gb] Exiting with exception: IOError([Errno 2] No such file or directory: '1529209968_sdp_l0_1284.full_pol_fg_wtspec_47Tuc_1k.ms/chain-field_0-ddid_None.parmdb')

however:

$ grep xfer dE-load-and-apply.parset
xfer-from =
xfer-from = {data[ms]}/{JONES}-field_{sel[field]}-ddid_{sel[ddid]}.parmdb
xfer-from = {data[ms]}/{JONES}-field_{sel[field]}-ddid_{sel[ddid]}.parmdb

which are respectively the options in the template, the [g] and the [dE] sections.

The word 'chain' doesn't appear in the parset anywhere. Full logs and parsets available on request.

Cheers.

Which branch are you on? I have pushed a fix to madmax-moreplots. It's a one-liner if you want to try it elsewhere:

Thanks, will give it a go. Am on 'master' in this case.

[IanHeywood]

It's working now, thanks. Will leave this open as I guess it needs to propagate into the master branch too.

Fixed in the merge.
