Input Arguments

collapse all

Nucleotide or amino acid sequence, specified as one of the following:

  • Character array or string vector containing a sequence

  • Character vector or string scalar containing the FASTA file name

  • Structure with the field Sequence

The seqdisp function supports multiply aligned sequences.

FASTA files can have the file extension fa, fasta, fas, fsa, or fst.

Data Types: char | string | struct

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example: seqdisp(mouseHEXA,Row=50) displays a sequence with rows of length 50.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

Example: seqdisp(mouseHEXA,"Row",50)

Length of each row, specified as a positive integer. The value of Row must be larger than and evenly divisible by the value of Column.

Column width or number of symbols before displaying a space, specified as a positive integer.

Display numbers at the start of each row, specified as a numeric or logical true (1) or false (0). Specify true to show numbers, or false to hide numbers.

Version History

Introduced before R2006a
