Basic Local Alignment Search Tool - BLAST
网页2024年7月22日 · The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches.
Nucleotide BLAST: Align two or more sequences using BLAST
网页QuickBLASTP is an accelerated version of BLASTP that is very fast and works best if the target percent identity is 50% or more. BlastP simply compares a protein query to a protein database. PSI-BLAST allows the user to build a PSSM (position-specific scoring matrix) using the results of the first BlastP run.
NCBI Bioinformatics Resources: An Introduction: BLAST: Compare ...
网页2024年8月6日 · BLASTn (Nucleotide BLAST): compares one or more nucleotide query sequences to a subject nucleotide sequence or a database of nucleotide sequences. This is useful when trying to determine the evolutionary relationships among different organisms (see Comparing two or more sequences below).
Sequence Alignment Tool - VectorBuilder
网页2 天之前 · VectorBuilder’s Sequence Alignment tool allows you to not only directly compare two sequences at the DNA or protein level, but also compare two DNA sequences based on translation. You can also design vectors containing your sequence of interest.
python - Elegant way to compare sequences - Stack Overflow
网页2009年5月23日 · Convert both sequences to lists, and use builtin list comparison. It should be sufficient, unless your sequences are really large. list(a) == list(b) Edit: Testing done by schickb shows that using tuples is slightly faster: tuple(a) == tuple(b) edited May 23, 2009 at 1:46. answered May 22, 2009 at 23:36.
MRI sequences (overview) | Radiology Reference Article - Radiopaedia.org
网页2022年9月4日 · An MRI sequence is a number of radiofrequency pulses and gradients that result in a set of images with a particular appearance. This article presents a simplified approach to recognizing common MRI sequences, but does not concern itself with the particulars of each sequence.

Tones and Semitones - Music Theory Academy - Easy music lesson
网页Tones. A tone (or whole step) is an interval of 2 semitones (or half steps) added together. For example, the interval between C and D is a tone because the note C sharp/D flat is between them: Vm. Tone C to D. P. d. Similarly, the interval between A and B is a tone (the note A sharp/B flat is between the 2 notes): Vm.
Basics of Twelve-Tone Theory – Open Music Theory
网页Key Takeaways. Twelve-tone composition involves using all twelve pitch classes roughly equally. That means it (usually) isn’t appropriate to look for a key, mode, tonic pitch, or other tonal elements. Composers often use a fixed ordering of the twelve pitch classes called a row, but also adapt it in various ways, notably through: Transposition (T)
The auditory dynamic attending theory revisited: A closer look …
网页2015年11月11日 · Rev. 83 (5), 323–355 posits that tone sequences presented at a regular rhythm entrain attentional oscillations and thereby facilitate the processing of sounds presented in phase with this rhythm. The increased interest in neural correlates of dynamic attending requires robust behavioral indicators of the phenomenon.
