Sentence examples for reference projections from inspiring English sources
Images of untilted and 30° tilted particles were assigned Euler angles by comparison with reference projections and back-projected to obtain a new volume, which served as a reference during the next refinement iteration.
Some useful strategies of coordination are implemented in a perceptive frame by reference projections.
The Transform Class is also responsible for generating point-group symmetry operations as well as generating quasi-evenly distributed points on the sphere (which is used in creating reference projections for structure refinement procedures in single particle reconstruction).
After aligning each of the raw particle images with the reference calculated from the partial volume, we should be able to subtract reference projections from the raw micrographs directly.
Masking away the yellow part from the reconstruction in masked refinements yields reference projections that only contain the red part.
Previous approaches to masked classification in RELION (Amunts et al., 2014 ; Wong et al., 2014 ) compared experimental particles (panel D), with reference projections of only V2 (panel F).
ChemGPS creates a PCA reference projection based on drug-like and satellite molecules in property space to classify new compounds.
Each subclass was further refined using SPIDER according to standard reference projection matching procedures (Shaikh et al., 2008a).
Therefore, the yellow part of the signal will act as an additional source of noise in the comparison between the experimental image and the masked reference projection.
This results in a modified experimental particle image that only contains experimental noise and the CTF-affected projection of V2, so that comparison with the reference projection in panel F becomes consistent.
Explanation of the file types:.bmp = reconstructed images (multiple files), reference reconstruction (single file);.crv = preview file when setting projection or reconstruction parameters;.log = log file listing scan parameters;.roi = 2D region of interest (ROI) used to create a 3D volume of interest;.tif = projection images (multiple files), reference projection (single file).
