abstract = {LiberTEM is an open source platform for high-throughput
distributed processing of large-scale binary data sets using
a simplified MapReduce programming model. The current focus
is pixelated scanning transmission electron microscopy
(STEM) and scanning electron beam diffraction data. It is
designed for high throughput and scalability on PCs, single
server nodes, clusters and cloud services. On clusters it
can use fast distributed local storage on high-performance
SSDs. That way it achieves very high aggregate IO
performance on a compact and cost-efficient system built
from stock components. LiberTEM is supported on Linux, Mac
OS X and Windows. Other platforms that allow installation of
Python 3 and the required packages will likely work as well.
The GUI is running in a web browser. InstallationThe short
version: $ virtualenv -p python3.6 ~/libertem-venv/ $ source
~/libertem-venv/bin/activate (libertem) $ pip install
libertem[torch] Please see our documentation for details!
Deployment as a single-node system for a local user is
thoroughly tested and can be considered stable. Deployment
on a cluster is experimental and still requires some
additional work, see Issue #105. Applications Virtual
detectors (virtual bright field, virtual HAADF, center of
mass , custom shapes via masks) Analysis of amorphous
materials Strain mapping Custom analysis functions
(user-defined functions) Please see the applications section
of our documentation for details! The Python API and
user-defined functions (UDFs) can be used for more complex
operations with arbitrary masks and other features like data
export. There are example Jupyter notebooks available in the
examples directory. If you are having trouble running the
examples, please let us know, either by filing an issue or
by joining our Gitter chat. LiberTEM is suitable as a
high-performance processing backend for other applications,
including live data streams. Contact us if you are
interested! LiberTEM is evolving rapidly and prioritizes
features following user demand and contributions. In the
future we'd like to implement live acquisition, and more
analysis methods for all applications of pixelated STEM and
other large-scale detector data. If you like to influence
the direction this project is taking, or if you'd like to
contribute, please join our gitter chat and our general
mailing list. File formatsLiberTEM currently opens most file
formats used for pixelated STEM. See our general information
on loading data and format-specific documentation for more
information! Raw binary files Thermo Fisher EMPAD detector
files Quantum Detectors MIB format Nanomegas .blo block
files Gatan K2 IS raw format Gatan DM3 and DM4: See Issue
#291 Please contact us if you would like to process such
data! FRMS6 from PNDetector pnCCD cameras (currently alpha,
gain correction still needs UI changes) FEI SER files (via
openNCEM) HDF5-based formats such as Hyperspy files, NeXus
and EMD Please contact us if you are interested in support
for an additional format! LicenseLiberTEM is licensed under
