DU8:iTOL的配置文件
iTOL除了可以用control面板调整进化树的性状，分支颜色，标签字体等之外，还可以利用配置文件进行批量修改，配置文件直接拖到进化树上。
配置文件需要包括的信息：
1、dataset的类型
TREE_COLORS
2、指定文件分隔符
SEPARATOR TAB
SEPARATOR SPACE
SEPARATOR COMMA
3、按照不同dataset的模板设置注释信息
DATA
"Template"
以下为不同dataset的模板：
1、Branch and label colors and styles
前3列表示节点数据，类型（5种），颜色
range: defines a colored range (colored background for labels/clade)
clade: defines color/style for all branches in a clade
branch: defines color/style for a single branch
label: defines font color/style for the leaf label
label_background: defines the leaf label background color
不同类型的其他列有差异
for range, field 4 defines the colored range label (used in the legend)
for label, field 4 defines the font style ('normal','bold', 'italic' or 'bold-italic') and field 5 defines the numeric scale factor for the font size (eg. with value 2, font size for that label will be 2x the standard size)
for clade and branch, field 4 defines the branch style ('normal' or 'dashed') and field 5 defines the branch width scale factor (eg. with value 0.5, branch width for that clade will be 0.5 the standard width)

2、Changing leaf labels text and internal node names
LABELS
SEPARATOR TAB
DATA
9031|9606 Metazoa
9606 Homo sapiens
3、Defining node popup information
POPUP_INFO
SEPARATOR COMMA
DATA
#NODE_ID,POPUP_TITLE,POPUP_CONTENT
#internal node with simple HTML in its popup
9031|9606,This is the popup title,<h1>Some header</h1><p>Information comes here</p><img src='http://website.com/images/image.jpg'/>
#popup for leaf node 9606
9606,Homo sapiens info popup,<h1>Homo sapiens</h1><p style='color:blue'>More info at <a target='_blank' href='http://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?id=9606'>NCBI</a></p>
4、Binary
标记形状
1: rectangle
2: circle
3: star
4: right pointing triangle
5: left pointing triangle
6: check mark
标记形状是否填充颜色及显示
1 : filled shape
0 : empty shape
-1 : shape completely omitted
DATASET_BINARY
SEPARATOR COMMA
#label is used in the legend table (can be changed later)
DATASET_LABEL,label1
#dataset color (can be changed later)
FIELD_SHAPES,2,4,5,1
