abstract = {Technological progress in neuroscience allows recording
from tens to hundreds of neuronssimultaneously, both in
vitro and in vivo, using various recording techniques (e.g.,
multi-electrode recordings) and stimulation methods (e.g.,
optogenetics). In addition, recordingscan be performed in
parallel from multiple brain areas, under more or less
naturalconditions in (almost) freely behaving animals.
Consequently, electrophysiologicalexperiments become
increasingly complex. Moreover, to disentangle the
relationship tobehavior, it is necessary to document animal
training, experimental procedures, and detailsof the setup
along with recorded neuronal and behavioral data.
Considering this, availabilityof the information about the
experimental conditions, commonly referred to as metadata,
isof extreme relevance for reproducible data analysis and
correct interpretation of results.Typically, experimenters
have developed their own personal procedure to document
theirexperiment, allowing at best other members of the lab
to share data and metadata.However, at the latest when it
comes to data sharing across labs, details may be missed.
Inparticular if collaborating groups have different
scientific backgrounds, implicit knowledge isoften not
communicated. In order to perform interpretable analysis,
each data set shouldtherefore clearly link to metadata
annotations about experimental conditions such as
theperformed task, quality of the data, or relevant
preprocessing (e.g., spike sorting).In order to provide
metadata in an organized, easily accessible, but also
machine-readableway, an XML based file format, odML (open
metadata Markup Language), was proposed [1].Here we will
demonstrate the usefulness of standardized metadata
collections for handlingthe data and their analysis in the
context of a complex behavioral (reach to grasp)experiment
with neuronal recordings from a large number of electrodes
(Utah array)delivering massively parallel spike and LFP data
[2]. We illustrate the conceptual design ofan odML metadata
structure and provide a practical introduction on how to
generate anodML file. In addition, we offer odML templates
to facilitate the usage of odML acrossdifferent laboratories
and experimental contexts. We demonstrate hands-on the
advantagesof using odML to screen large numbers of data sets
according to selection criteria (e.g.,behavioral
performance) relevant for subsequent analyses (see companion
posters byDenker et al. and Riehle et al.). Well organized
metadata management is a key componentto guarantee
reproducibility of experiments and to track provenance of
performed analyses.},
