To determine the significance of an occurrence, we compared several theoretical distributions to the empirical score distribution, but none approximated the alignment scores well.
The beginnings and ends of the small and large rRNA subunits, 918 bp and 1718 bp, respectively, were approximated from alignment data as these genes retained little sequence similarity to the rRNAs from sequenced demosponge mtDNAs, or with those in the non-redundant BLAST database.
The new IEC 60261 has provided an approximate alignment of SIL ratings with the safety categories as defined by EN 954.
A second stage fine alignment is then used to accurately register the scans from the first approximate alignment.
The initial, approximate alignment of the point cloud with the camera image can be used to perform stereo calibration.
Second, when a fingerprint "bit" was in common between two conformers, the retained alignments to the reference shape were used to yield an (approximate) alignment between the conformers.
On the other hand, we observed that 48 angular divisions for the highest resolution level are sufficient to obtain an acceptable approximate alignment.
Although the NW algorithm represents the gold standard for accuracy, it is computationally intensive compared to approximate alignment methods.
After impalement of a photoreceptor and approximate alignment of the light source with its optical axis, the receptor was characterized by its spectral sensitivity, which was measured with the spectral scan method [33].
This is an important result as it shows the necessity of approximate alignment algorithms.
To increase computational efficiencies, two approximate alignment methods have been developed, which separate the translational from the rotational subtomogram alignments (Bartesaghi et al., 2008; Xu et al., 2012).
