  2. Plant growth analysis - Wikipedia

    en.wikipedia.org/wiki/Plant_growth_analysis

    A time-course of RGR can be estimated by fitting a non-linear equation through the ln-transformed size data, and calculating the derivative with respect to time. [5] For plants RGR values are typically (much) smaller than 1 g.g −1 .day −1 .

  3. Relative growth rate - Wikipedia

    en.wikipedia.org/wiki/Relative_growth_rate

    In the simplest case of observations at two time points, RGR is calculated using the following equation: [1] = ⁡ - ⁡ - , where: = natural logarithm = time one (e.g. in days)

  4. N50, L50, and related statistics - Wikipedia

    en.wikipedia.org/wiki/N50,_L50,_and_related...

    The size of assembly B is 305 kbp, the N50 contig length drops to 50 kbp because 80 + 70 + 50 is greater than 50% of 305, and the L50 contig count is 3 contigs. This example illustrates that one can sometimes increase the N50 length simply by removing some of the shortest contigs or scaffolds from an assembly.

  5. Log-normal distribution - Wikipedia

    en.wikipedia.org/wiki/Log-normal_distribution

    The length of inert appendages (hair, claws, nails, teeth) of biological specimens, in the direction of growth. [citation needed] The normalised RNA-Seq readcount for any genomic region can be well approximated by log-normal distribution. The PacBio sequencing read length follows a log-normal distribution. [68]

  6. Mean line segment length - Wikipedia

    en.wikipedia.org/wiki/Mean_line_segment_length

    Monte Carlo method to approximate the mean line segment length of a unit square. Since computing the mean line segment length involves calculating multidimensional integrals, various methods for numerical integration can be used to approximate this value for any shape. One such method is the Monte Carlo method. To approximate the mean line ...

  7. R (programming language) - Wikipedia

    en.wikipedia.org/wiki/R_(programming_language)

    R is a programming language for statistical computing and data visualization. It has been adopted in the fields of data mining, bioinformatics and data analysis. [9] The core R language is augmented by a large number of extension packages, containing reusable code, documentation, and sample data. R software is open-source and free software.

  8. Renormalization group - Wikipedia

    en.wikipedia.org/wiki/Renormalization_group

    The RG transformation proceeds by integrating out a certain set of high-momentum (large-wavenumber) modes. Since large wavenumbers are related to short-length scales, the momentum-space RG results in an essentially analogous coarse-graining effect as with real-space RG. Momentum-space RG is usually performed on a perturbation expansion.

  9. Binary Alignment Map - Wikipedia

    en.wikipedia.org/wiki/Binary_Alignment_Map

    Binary Alignment Map (BAM) is the comprehensive raw data of genome sequencing; [1] it consists of the lossless, compressed binary representation of the Sequence Alignment Map-files. [2] [3] BAM is the compressed binary representation of SAM (Sequence Alignment Map), a compact and index-able representation of nucleotide sequence alignments. [4]
