The original FASTA/Pearson format is described in the documentation for the FASTA suite of programs. It can be downloaded with any free distribution of FASTA (see fasta20.doc, fastaVN.doc, or fastaVN.me—where VN is the Version Number).
The Pearson symbol, or Pearson notation, is used in crystallography as a means of describing a crystal structure. [1] It was originated by W. B. Pearson and is used extensively in Peason's handbook of crystallographic data for intermetallic phases. [2] The symbol is made up of two letters followed by a number. For example: Diamond structure, cF8
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
The size taken for a word, given by the parameter kmer, controls the sensitivity and speed of the program. Increasing the k-mer value decreases number of background hits that are found. From the word hits that are returned the program looks for segments that contain a cluster of nearby hits. It then investigates these segments for a possible match.
From the “File” menu, choose “Apply document settings from → ACS Document 1996”. Draw the structure, and save it as a ChemDraw file. If you drew the structure before applying any settings, then you need to select the object, open the “Object” menu and choose “Apply document settings from → ACS Document 1996”.

A Pearson density p is defined to be any valid solution to the differential equation (cf. Pearson 1895, p. 381) ′ () + + + + = ()with: =, = = +, =. According to Ord, [3] Pearson devised the underlying form of Equation (1) on the basis of, firstly, the formula for the derivative of the logarithm of the density function of the normal distribution (which gives a linear function) and, secondly ...
