which implements an accurate,
unbiased, reproducible, and fast method to measure the morphological
parameters of a population of nanoparticles (NPs) from TEM micrographs.
The morphological parameters of the projected NP shape are obtained by
fitting intensity models to the TEM micrograph. PEBBLES can be used
either in automatic mode, where both fitting and validation are
reliably carried out with minimal human intervention, and in manual
mode, where the user has full control on the fitting and validation
steps. When operated in automatic mode, PEBBLES can be very fast. The
effective speed of 1 NP/sec has been achieved in favorable cases.
Since PEBBLES is based on a local modeling procedure, it successfully
treats cases such as low contrast NPs, NPs with significant diffraction
scattering, and inhomogeneous background which often make conventional
thresholding procedures fail. PEBBLES is accompanied by PEBBLEJUGGLER,
a software for the statistical analysis of the sets of best-fit NP
models created by PEBBLES. Effort has been devoted to make PEBBLES and
PEBBLEJUGGLER the most user-friendly and the least user-tedious we
could.
