Code quality
=============================
For usability and reliability of the software the code needs to be high quality. For this
project it means meeting the four criteria described below. Any addition should pass all of
them.
--------------------------------
Look, read and feel like Python
--------------------------------
When using classes and functions from the
package it should feel like you are using Python tools and be forces
to write C++ style code with Python syntax.
::
with xray_box.shutter_open():
for th in threshold:
d.vthreshold = th
d.acq()
should be preferred over
::
N = len(threshold)
xray_box.open_shutter()
for i in range(N):
d.dacs.set_dac('vthreshold', threshold[i])
d.acq()
xray_box.close_shutter()
even if the difference might seem small.
--------------------
Have documentation
--------------------
Classes and functions should be documented with doc-strings
in the source code. Preferably with examples. The syntax to be used
is numpy-sphinx.
::
def function(arg):
"""
This is a function that does something
Parameters
----------
arg: int
An argument
Returns
--------
value: double
Returns a value
"""
return np.sin(arg+np.pi)
---------------------------------
Pass static analysis with pylint
---------------------------------
Yes, anything less than 9/10 just means that you are lazy. If
there is a good reason why to diverge, then we can always
add an exception.
Currently the following additions are made:
* good-names: x, y, ax, im etc.
* function arguments 10
* Whitelist: numpy, _sls
-----------------------
Tested code
-----------------------
Last but not least... *actually last just because of the long list included.*
All code that goes in should have adequate tests. If a new function does not
have a minimum of one test it does not get added.
**Unit-tests with pytest and mocker**

Error handling
=========================
Check input in Python
----------------------
As far as possible we try to check the input on the Python side
before calling the slsDeteectorsSoftware. Errors should not pass
silently but raise an exception
::
#Trimbit range for Eiger is 0-63
detector.trimbits = 98
(...)
ValueError: Trimbit setting 98 is outside of range:0-63
Errors in slsDetectorsSoftware
-------------------------------
The slsDetectorsSoftware uses a mask to record errors from the different
detectors. If an error is found we raise a RuntimeError at the end of the
call using the error message from slsDetectorsSoftware
.. todo ::
Implement this for all functions
::
detector.settings = 'bananas'
(...)
RuntimeError: Detector 0:
Could not set settings.
Detector 1:
Could not set settings.
Detector 2:
Could not set settings.
Using decorators
-------------------
Using decorators we can reset the error mask before the command and then
check it after the command
.. code-block:: python
#add decorator to check the error mask
@error_handling
def some_function():
a = 1+1
return a
Communication with the detector is usually the biggest overhead so
this does not impact performance.
::
%timeit d.exposure_time
>> 1.52 ms ± 5.42 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
%timeit d.decorated_exposure_time
>> 1.53 ms ± 3.18 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

Examples
================
Some short hints on how to use the detector
------------------------
Simple threshold scan
------------------------
Assuming you have set up your detector with exposure time, period, enabled
file writing etc.
.. code-block:: python
from sls_detector import Eiger
d = Eiger()
threshold = range(0, 2000, 200)
for th in threshold:
d.vthreshold = th
d.acq()
If we want to control the shutter of for example, the big X-ray box we can add
this line in our code. It then opens the shutter just before the measurement
and closes is afterwards.
::
with xrf_shutter_open(box, 'Fe'):
for th in threshold:
d.vthreshold = th
d.acq()
-----------------------
Reading temperatures
-----------------------
::
d.temp
>>
temp_fpga : 43.19°C, 51.83°C
temp_fpgaext : 38.50°C, 38.50°C
temp_10ge : 39.50°C, 39.50°C
temp_dcdc : 42.50°C, 42.50°C
temp_sodl : 39.50°C, 40.50°C
temp_sodr : 39.50°C, 40.50°C
temp_fpgafl : 40.87°C, 37.61°C
temp_fpgafr : 34.51°C, 35.63°C
d.temp.fpga
>> temp_fpga : 40.84°C, 39.31°C
t = d.temp.fpga[0]
t
>> 40.551
t = d.temp.fpga[:]
t
>> [40.566, 39.128]
-----------------------
Non blocking acquire
-----------------------
There are mainly two ways to achieve a non blocking acquire when calling from the Python API. One is to manually start
the detector and the second one is to launch the normal acquire from a different process. Depending on your measurement
it might also be better to run the other task in a seperate process and use acq in the main thread.
But lets start looking at the at the manual way:
::
import time
from sls_detector import Eiger
d = Eiger()
n = 10
t = 1
d.exposure_time = t
d.n_frames = n
d.reset_frames_caught()
#Start the measurement
t0 = time.time()
d.start_receiver()
d.start_detector()
#Wait for the detector to be ready or do other important stuff
time.sleep(t*n)
#check if the detector is ready otherwise wait a bit longer
while d.status != 'idle':
time.sleep(0.1)
#Stop the receiver after we got the frames
#Detector is already idle so we don't need to stop it
d.stop_receiver()
lost = d.frames_caught - n
print(f'{n} frames of {t}s took {time.time()-t0:{.3}}s with {lost} frames lost ')
#Reset to not interfere with a potential next measurement
d.reset_frames_caught()
Instead launching d.acq() from a different process is a bit easier since the control of receiver and detector
is handled in the acq call. However, you need to join the process used otherwise a lot of zombie processes would
hang around until the main process exits.
::
import time
from multiprocessing import Process
from sls_detector import Eiger
def acquire():
"""
Create a new Eiger object that still referes to the same actual detector
and same shared memory. Then launch acq.
"""
detector = Eiger()
detector.acq()
#This is the detector we use throughout the session
d = Eiger()
#Process to run acquire
p = Process(target=acquire)
#Start the thread and short sleep to allow the acq to start
p.start()
time.sleep(0.01)
#Do some other work
while d.busy is True:
print(d.busy)
time.sleep(0.1)
#Join the process
p.join()

Getting started
================
------------------------
Setting up the detector
------------------------
All configuration of the detector can either be done from the Python
API (including loading config file) or externally. The detector setup is
discovered from the shared memory when launching a new script. Because the
detector usually should remain online longer than a specific script it is
recommended to run the receivers seperate.
---------------------------------
Setting and getting attributes
---------------------------------
Most of the detector and software setting are implemented as attributes
in the Detector class. When something is assigned it is also set
in the detector and when the attribute is called using dot notation it
it looked up from the detector.
::
#Currently Eiger and Jungfrau but Detector should work for all
from sls_detector import Eiger()
d = Eiger()
d.file_write = True
d.vthreshold = 1500
d.frame_index
>> 12
d.file_name
>> 'run'
---------------------------------
Working with DACs
---------------------------------
The following examples assumes an Eiger500k detector. But the same syntax
works for other detector sizes and models.
::
d.dacs
>>

vrf = d.dacs.vrf[:]
#Set a dac in a module
d.dacs.vrf[0] = 1500
d.dacs.vrf[0]
>> 1500
#Set vrf to the same value in all moduels
d.dacs.vrf = 1500
#Set a dac using an iterable
d.dacs.vrf = [1500, 1600]
d.dacs.vrf
>> vrf : 1500, 1600
#Set dacs iterating on index and values
d.dacs.vrf[0,1] = 1300,1400
---------------------------------
Operating multiple detectors
---------------------------------
Operating multiple detectors is supported by assigning an id when creating the object. If no id is
set it defaults to 0.
::
d0 = Eiger() #id is now 0
d1 = Jungfrau(1)
#Or explicitly
d1 = Jungfrau(id = 0)
The detectors now operate independently of each other but can be synchronized using a hardware trigger.
::
from sls_detector import Eiger
d0 = Eiger(0)
d1 = Eiger(1)
d0.load_config('/some/path/T45.config')
d1.load_config('/some/path/T62.config')
d0.n_frames = 1
d0.exposure_time = 1
d0.timing_mode = 'trigger'
d1.n_frames = 5
d1.exposure_time = 0.2
d1.timing_mode = 'trigger'

Installation
=========================
The easiest way to install the Python API and the slsDetectorPackage is using conda. But other
methods are also available.
---------------------
Install using conda
---------------------
If you don't have it installed get the latest version of `Miniconda`_
.. _Miniconda: https://conda.io/miniconda.html
::
wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh
sh Miniconda3-latest-Linux-x86_64.sh
Install sls_detector and sls_detector_lib using:
::
#Add conda channels
conda config --add channels conda-forge
conda config --add channels slsdetectorgroup
#Install latest version
conda install sls_detector
#Install specific version
conda install sls_detector=3.0.1
------------------------------
Local build using conda-build
------------------------------
Needs the `sls_detector_lib`_ installed in order to automatically find headers
and shared libraries. Make sure that the branch of sls_detector matches the lib
version installed.
.. _sls_detector_lib: https://github.com/slsdetectorgroup/sls_detector_lib
::
#Clone source code
git clone https://github.com/slsdetectorgroup/sls_detector.git
#Checkout the branch needed
git checkout 3.0.1
#Build and install the local version
conda-build sls_detector
conda install --use-local sls_detector
-----------------------
Developer build
-----------------------
IF you if you are developing and are making constant changes to the code it's a bit cumbersome
to build with conda and install. Then an easier way is to build the C/C++ parts in the package
directory and temporary add this to the path
::
#in path/to/sls_detector
python setup.py build_ext --inplace
Then in your Python script
::
import sys
sys.path.append('/path/to/sls_detector')
from sls_detector import Detector
--------------
Prerequisites
--------------
All dependencies are manged trough conda but for a stand alone build you would need
* gcc 4.8+
* Qwt 6
* Qt 4.8
* numpy
* slsDetectorPackage
