title: Extensive Angular Sampling Enables the Sensitive Localization of Macromolecules in Electron Tomograms | ||
abstract: >- | ||
Cryo-electron tomography provides 3D images of | ||
macromolecules in their cellular context. To detect | ||
macromolecules in tomograms, template matching (TM) is | ||
often used, which uses 3D models that are often reliable | ||
for substantial parts of the macromolecules. However, the | ||
extent of rotational searches in particle detection has | ||
not been investigated due to computational limitations. | ||
Here, we provide a GPU implementation of TM as part of the | ||
PyTOM software package, which drastically speeds up the | ||
orientational search and allows for sampling beyond the | ||
Crowther criterion within a feasible timeframe. We | ||
quantify the improvements in sensitivity and | ||
false-discovery rate for the examples of ribosome | ||
identification and detection. Sampling at the Crowther | ||
criterion, which was effectively impossible with CPU | ||
implementations due to the extensive computation times, | ||
allows for automated extraction with high sensitivity. | ||
Consequently, we also show that an extensive angular | ||
sample renders 3D TM sensitive to the local alignment of | ||
tilt series and damage induced by focused ion beam | ||
milling. With this new release of PyTOM, we focused on | ||
integration with other software packages that support more | ||
refined subtomogram-averaging workflows. The automated | ||
classification of ribosomes by TM with appropriate angular | ||
sampling on locally corrected tomograms has a sufficiently | ||
low false-discovery rate, allowing for it to be directly | ||
used for high-resolution averaging and adequate | ||
sensitivity to reveal polysome organization. | ||
