yaqd edit-config horiba-micro-hr will open up notepad (or actually whatever is in $EDITOR) with that file directly
I don’t think we have set up a DOI for the project itself (via e.g. Zenodo). Here is a paper that people cite: https://www.tandfonline.com/doi/full/10.1080/08940886.2019.1608121 (DOI: https://doi.org/10.1080/08940886.2019.1608121)

Hi, Bluesky mates. The following code:
ThetaS = EpicsMotor('31a:DCM:ThetaS', name='ThetaS')
print('ThetaS position', ThetaS.position)
will cause exception DisconnectedError:
Traceback (most recent call last):
File "ztest_ac.py", line 69, in <module>
print('ThetaS position', ThetaS.position)
File "/home/chiang.lc/anaconda3/envs/py37bluesky/lib/python3.7/site-packages/ophyd/utils/epics_pvs.py", line 200, in wrapper
raise DisconnectedError('{} is not connected'.format(self.name))
ophyd.utils.errors.DisconnectedError: ThetaS is not connected
In the same environment, I can use pyepics module ( motor = epics.Motor('31a:DCM:ThetaS') ) to move the motor and to read its position without any problem.
Would you please provide hints for debugging and finding causes?
print('ThetaS.read()', ThetaS.read())
ophyd.utils.errors.DisconnectedError: ThetaS is not connected
suitcase.csv.export will raise exception ValueError: I/O operation on closed file.
The 'export' does successfully create and write to a csv file though.

LivePlot to be able to deal with 1D vectors or use it as a template and write a new callback that deals with the vectors. It is not clear to me if you got N events each of which had a vector do you want to concatenate them into one line or plot them each as their own line.
Dear all,
I am using bluesky / ophyd for executing measurement scripts on the BESSY II accelerator: e.g. orbit response matrix or beam based alignment measurements.These scripts need to configure ophyd devices dependent on the state of the machine. Personnaly I find ophyds config variables and configure() method quite convienient as long as one only has to deal with one or two devices.
I'd like to ask if there is a tool that facilitates configuring a lot of ohpyd devices similar to e.g. epics save/restore.
Thanks for any answer!

- Why the nxs file be stored separately from raw hdf5 files？
- Is it necessary to slice the data collected by the detector for storage? If yes, why is it necessary to slice the data collected by the detector and store it as separate hdf5 files?
- How do the nxs file store data when multiple detectors are collecting data at the same time?
- NeXus is hdf5 with a specific structure. Using this structure with defined names for The things in the files helps us understand what the data in the file is.

The solved broker Issue bluesky/databroker#343 works when using
count() but not with sleep().Other callback like
LiveTable() register all events.# python -m caproto.ioc_examples.thermo_sim
class Thermo(Device):
readback = Component(EpicsSignalRO, 'I')

cb = bcb.LiveTable([thermo], stream_name="thermo_readback_monitor")
RE.subscribe(cb)
