# Description: Supports visualizing multiple sequence alignment of DNA and protein sequences using 'ggplot2'. It supports a number of colour schemes, including Chemistry, Clustal, Shapely, Taylor and Zappo. Multiple sequence alignment can easily be combined with other 'ggplot2' plots, such as aligning a phylogenetic tree produced by 'ggtree' with multiple sequence alignment.

# Plot multiple sequence alignment using ggplot2 with multiple color schemes supported.
# Supports visualizing multiple sequence alignment of DNA and protein sequences using ggplot2 It supports a number of colour schemes, including Chemistry, Clustal, Shapely, Taylor and Zappo. Multiple sequence alignment can easily be combined with other ‘ggplot2’ plots, such as aligning a phylogenetic tree produced by ‘ggtree’ with multiple sequence alignment.
### 4.1 Load sample data
# Three sample data are shipped with the ggmsa package. Note that ggmsa supports not only fasta files but other objects as well. available_msa()can be used to list MSA objects currently available.
available_msa()
# files currently available:
#? .fasta
# XStringSet objects from 'Biostrings' package:
#? DNAStringSet RNAStringSet AAStringSet BStringSet DNAMultipleAlignment RNAMultipleAlignment AAMultipleAlignment
# bin objects from 'seqmagick' package:
#? DNAbin AAbin

# Visualizing Multiple Sequence Alignments #
### 4.2 The most simple code to use ggmsa:
?ggmsa
#@ 簡(jiǎn)單繪制
ggmsa(protein_sequences, start = 265, end = 300)
#@ 調(diào)整參數(shù)，實(shí)現(xiàn)個(gè)性化繪制多序列比對(duì)圖
ggmsa(protein_sequences, start = 265, end = 300, font = "TimesNewRoman", color = "Clustal", char_width = 0.8, none_bg = T, seq_name = T)
ggmsa(protein_sequences, start = 265, end = 300, font = "TimesNewRoman", color = "Chemistry_AA", char_width = 0.8, none_bg = F)
# Colour Schemes #
available_colors()
# color schemes for nucleotide sequences currently available:
#? Chemistry_NT Shapely_NT Taylor_NT Zappo_NT
# color schemes for AA sequences currently available:
#? Clustal Chemistry_AA Shapely_AA Zappo_AA Taylor_AA
### 4.3 Clustal X Colour Scheme(Default)
#@ This is an emulation of the default colourscheme used for alignments in Clustal X, a graphical interface for the ClustalW multiple sequence alignment program. Each residue in the alignment is assigned a colour if the amino acid profile of the alignment at that position meets some minimum criteria specific for the residue type.
ggmsa(protein_sequences, start = 320, end = 360, color = "Clustal")
### 4.4 Color by Chemistry
#@ Amino acids are colored according to their side chain chemistry:
ggmsa(protein_sequences, start = 320, end = 360, color = "Chemistry_AA")
### 4.5 Color by Shapely
#@ This color scheme matches the RasMol amino acid and RasMol nucleotide color schemes, which are, in turn, based on Robert Fletterick’s “Shapely models”.
ggmsa(protein_sequences, start = 320, end = 360, color = "Shapely_AA")
### 4.6 Color by Taylor
#@ This color scheme is taken from Taylor(Taylor 1997) and is also used in JalView(Waterhouse et al. 2009).
ggmsa(protein_sequences, start = 320, end = 360, color = "Taylor_AA")
### 4.7 Color by Zappo
#@ This scheme colors residues according to their physico-chemical properties, and is also used in JalView(Waterhouse et al. 2009).
ggmsa(protein_sequences, start = 320, end = 360, color = "Zappo_AA")
### 4.8 Font
#@ Several classic font for MSA are shipped in the package. In the same ways, you can use available_fonts() to list font currently available
available_fonts()
# font families currently available:
? # helvetical mono TimesNewRoman DroidSansMono
# helvetical
ggmsa(protein_sequences, start = 320, end = 360, font = "helvetical", color = "Chemistry_AA")
# TimesNewRoman
ggmsa(protein_sequences, start = 320, end = 360, font = "TimesNewRoman", color = "Chemistry_AA")
# DroidSansMono
ggmsa(protein_sequences, start = 320, end = 360, font = "DroidSansMono", color = "Chemistry_AA")
#@ If you specify font = NULL, only tiles will be plot.
ggmsa(protein_sequences, start = 320, end = 360, font = NULL, color = "Chemistry_AA", seq_name = F)
ggmsa(protein_sequences, start = 320, end = 360, font = NULL, color = "Chemistry_AA", seq_name = T)
### 4.9 Characters width
#@ Characters width can be specified by char_width. Defaults is 0.9.
ggmsa(protein_sequences, start = 320, end = 360, char_width = 0.5, color = "Chemistry_AA")
### 4.10 Background
#@ Background can be specified by none_bg. If none_bg = TRUE, only the character will be plot.
ggmsa(protein_sequences, start = 320, end = 360, none_bg = TRUE) + theme_void()
### 4.11 Position Highligthed
#@ Position Highligthed can be specified by posHighligthed. The none_bg = FALSE when you specified position Highligthed by posHighligthed
# 不連續(xù)高亮
ggmsa(protein_sequences, 164, 213, color = "Chemistry_AA",
? ? ? posHighligthed = c(185, 190))
ggmsa(protein_sequences, 164, 213, color = "Chemistry_AA", posHighligthed = c(180, 190, 200))
# 連續(xù)高亮
ggmsa(protein_sequences, 164, 213, color = "Chemistry_AA",
? ? ? posHighligthed = c(180:200))
### 4.12 Sequence names
#@ Sequence names Defaults is ‘NULL’ which indicates that the sequence name is displayed when font = NULL, but ‘font = char’ will not be displayed. If seq_name = TRUE the sequence name will be displayed when you need it.
ggmsa(protein_sequences, 164, 213, color = "Chemistry_AA", seq_name = TRUE)
#2 If seq_name = FALSE the sequence name will not be displayed in any case.
ggmsa(protein_sequences, 164, 213, font = NULL, color = "Chemistry_AA", seq_name = FALSE)
