It requires selecting comparison source, which is set to shuffled sequences by default.
This dataset is split: a prediction set contains randomly selected sequences from the input dataset (20% of the sequences by default) and is used for motif prediction with several different computational tools.
Online localization is performed against masked genomic sequence by default as this ensures that results are returned quickly and that relatively few correct localizations are missed, despite the fact that as much as 50% of the genome consists of repeated elements [ 17].
Since BLAST excludes regions with low sequence complexity by default, the sequence complexity filter was explicitly disabled (option '-F F').
For genomic positions with sufficient sequencing depth (by default, >20 reads total from tumor and normal specimens), the script extracts sequencing depth, determines homozygous and heterozygous positions in the normal specimen, and calculates the variant alleles and allelic frequency from the tumor specimen.
In addition, option 3 can be applied to filter out edges between sequences, when the number of identical bases represents more than a minimal percentage of the shortest sequence length (by default 20%).
When make_integer_stream is called for the first time, it returns a stream whose first is the first integer in the sequence (1 by default).
Unlike tiling arrays whose resolution is limited by the number of probes on the platform, sequencing provides, by default, the best possible resolution.
The unambiguously aligned 16s rRNA sequences by Gblock (default parameters) were used to construct a phylogenetic tree using ML and Bayesian methods.
Levels of synonymous substitutions (Ks) were obtained by multiple alignment of all the tomato and potato rbcS coding sequences by CLUSTALW (default gap penalties), followed by estimation of the matrix of pairwise Ks values by the method of Li [ 80] implemented in the R package SEQINR [ 81].
It, too, started in "autoplay mode," serving up a continuous sequence of programs by default.
