pyABF 2.0.26

This release is on pypi.org/project/pyabf

pip install --upgrade pyabf

Minor Changes

• fixed bug that caused ABF1 gap-free files to get loaded with numerous sweeps (link)

pyABF 2.0.25

This release is on pypi.org/project/pyabf

pip install --upgrade pyabf

Minor Changes

• autoanalys code removed from pyABF (now in pyABFauto project)
• support for stimulus waveform caching (#59)

pyABF 2.0.24

This release is on pypi.org/project/pyabf

pip install --upgrade pyabf

Minor Changes

• Files are only opened using "with" statements (best practice)
• abfDateTimeString is still combined ISO 8061 standard but now is always exactly 23 characters: YYYY-MM-DDThh:mm:ss.sss (a fixed number of after-decimal seconds characters is what's new)
• abf._fileSize came back
• all "autoanalysis" code removed from pyABF (moved to the pyABFauto project)
• protocolStorageDir fixed in stimulus module (36ecc14)

pyABF 2.0.23

This release is on pypi.org/project/pyabf

pip install --upgrade pyabf

Minor Changes

• ABF1 file support for comments/tags
• abfDateTimeString now produces combined ISO 8061 standard always containing a "T" to separate date and time regardless of numpy version (previously some systems had a "T" and others had a space)
• several header output improvements (text, HTML, and markdown rendering)
  • data value precision limited and standardized
  • long lists of values are center-truncated to reduce file size
  • arrays are converted to strings manually to prevent header differences due to numpy version
  • abf header output can now be parsed/hashed and used for testing to ensure consistency

pyABF 2.0.21

This release coincides with a release on PyPi:

pip install --upgrade pyabf

Major Changes

• locking-in core API methods
• Action potential detection module
• Step-based membrane test module (with capacitance detection)
• Ramp-based capacitance detection module

pyABF 2.0.20

This release coincides with a release on PyPi:

pip install --upgrade pyabf

Minor Changes

• fix bug causing pyABF to crash when loading ABFs with unknown telegraphed instrument IDs

pyABF 2.0.18

This release coincides with a release on PyPi:

pip install --upgrade pyabf

Major Changes

• Improvements to the ABF header
• Support for custom stimulus waveforms
• ATF file reading support

pyABF 2.0.17

This release coincides with a release on PyPi:

pip install --upgrade pyabf

Major Changes

• Improved data data scaling and offset (discussed in #14 and NeuralEnsemble/python-neo#544)
• ABF acquisition date and time fix (discussed in #17)
• Epoch information and advanced interactive features are now part of an epoch object which lives in epochs.py.
  • A list of epochs (one per channel) is automatically created along with the ABF object and can be accessed as abf.epochsByChannel.
  • abf.epochsByChannel.text is a text formatted epoch table
  • Enhanced stimulus waveform creation for epochs with pulse trains, triangle trans, biphasic pulse trains, and cosine trains (discussed in #16).
  • Stimulus waveform generation for all known epoch types is now supported. To access a the stimulus waveform associated with abf.sweepY, just print or plot abf.sweepC.

Examples

Epoch Text Access Demo:

import pyabf
abf = pyabf.ABF("/18702001-biphasicTrain.abf")
print(abf.epochsByChannel[1].text)

Output:

                Ch1 EPOCH      A      B      C
                     Type   Step   Step BiPhsc
         First Level (mV)    -20    -10     25
         Delta Level (mV)      0      0     10
 First Duration (samples)   1000   4000  10000
 Delta Duration (samples)      0      0      0
   Train Period (samples)      0      0   1000
    Pulse Width (samples)      0      0    200

pyABF 2.0.11

First large release of pyABF version 2 to PyPi:
https://pypi.org/project/pyabf/

pip install --upgrade pyabf

It is a breaking change from pyABF 0.1.x, mostly due to the fact that abf.dataY was replaced with abf.sweepY.

pyABF 0.1.17

This is the final version of pyABF prior to v2, which will be a breaking release (mostly due to the switch from abf.dataY to abf.sweepY)
