lcm-log2smat is a python utility to convert Lightweight Communications and
Marshalling (LCM) logfiles to Matlab (.mat) or Python Pickle (.pkl) files.
The script converts a LCM logfile to a "structured" format that is easier to work with external tools such as Matlab or Python. The set of messages on a given channel is saved as a structure preserving the original LCM message structure. It works with nested messages, it is flexible and independent to the LCM message type definitions and it can be used as a script or imported as a Python module.
lcm-log2smat has been tested only on the GNU/Linux operating systems.
But it should work in other operating systems running Python.
The requirements are:
lcm-log2smat adheres to the Pods core policy, and makes use of the Pods
build tools. For more information about Pods, see:
https://sourceforge.net/p/pods/
You can install lcm-log2smat to your system by running:
$ sudo make BUILD_PREFIX=/usr/local
For a local installation, you can build lcm-log2smat inside the source
directory. To do this, run:
$ make
In this case, the executables, headers, libraries, etc. will be installed according to the Pods core policy. If no other "build" directory is found, it will default to: lcm-log2smat/build/
If compiled and installed to your system, run:
$ sudo make clean
Note: this can only be done from the lcm-log2smat source that was used for installation
To convert a LCM log file (data.lcm) to a Matlab file (data.mat)
$ lcm-log2smat data.lcm -o data.mat
To convert a LCM log file (data.lcm) to Python Pickle file (data.pkd)
$ lcm-log2smat data.lcm -k -o data.pkd
lcm-log2smat is based on libbot2
script bot-log2mat.
