export2graphlan是一个转换软件工具，用于为GraPhlAn生成注释和树文件
export2graphlan的Python项目详细描述
export2graphlan是一个转换软件工具，用于为GraPhlAn生成注释和树文件。特别是，注释文件试图突出显示从输入文件自动派生的特定子树，哪些节点是重要的。然后应该使用export2graphlan的两个输出文件来运行graphlan_annotate.py，以便将派生的注释附加到树上，最后，通过执行graphlan.py，用户可以获得输出图像。在
先决条件
export2graphlan需要以下附加库：
- 熊猫队。0.13.1（pandas）
- 生物模型版本。2.0.1（biom-format，仅当您有BIOM格式的输入文件时）
- SciPy（scipy，hclust2所需）
安装
export2graphlan在GitHub中提供：export2graphlan repository，可以使用以下方法获得：
$ conda install export2graphlan
- 存储库
这将在export2graphlan子文件夹中本地下载export2graphlan存储库。然后，您必须将此子文件夹放入系统路径中，以便您可以从系统中的任何位置使用export2graphlan：
$ export PATH=`pwd`/export2graphlan/:$PATH
将上述行添加到bash配置文件中将使路径添加成为永久性的。对于Windows或MacOS系统，应遵循类似的程序。在

export2graphlan.py (ver. 0.2.1 of 27 October 2018). Convert MetaPhlAn, LEfSe,
and/or HUMAnN output to GraPhlAn input format. Authors: Francesco Asnicar
(f.asnicar@unitn.it)
optional arguments:
-h, --help show this help message and exit
--annotations ANNOTATIONS
List which levels should be annotated in the tree. Use
a comma separate values form, e.g.,
--annotation_levels 1,2,3. Default is None
--external_annotations EXTERNAL_ANNOTATIONS
List which levels should use the external legend for
the annotation. Use a comma separate values form,
e.g., --annotation_levels 1,2,3. Default is None
--background_levels BACKGROUND_LEVELS
List which levels should be highlight with a shaded
background. Use a comma separate values form, e.g.,
--background_levels 1,2,3. Default is None
--background_clades BACKGROUND_CLADES
Specify the clades that should be highlight with a
shaded background. Use a comma separate values form
and surround the string with " if there are spaces.
Example: --background_clades "Bacteria.Actinobacteria,
Bacteria.Bacteroidetes.Bacteroidia,
Bacteria.Firmicutes.Clostridia.Clostridiales". Default
is None
--background_colors BACKGROUND_COLORS
Set the color to use for the shaded background. Colors
can be either in RGB or HSV (using a semi-colon to
separate values, surrounded with ()) format. Use a
comma separate values form and surround the string
with " if it contains spaces. Example:
--background_colors "#29cc36, (150; 100; 100), (280;
80; 88)". To use a fixed set of colors associated to a
fixed set of clades, you can specify a mapping file in
a tab-separated format, where the first column is the
clade (using the same format as for the "--
background_clades" param) and the second colum is the
color associated. Default is None
--title TITLE If specified set the title of the GraPhlAn plot.
Surround the string with " if it contains spaces,
e.g., --title "Title example"
--title_font_size TITLE_FONT_SIZE
Set the title font size. Default is 15
--def_clade_size DEF_CLADE_SIZE
Set a default size for clades that are not found as
biomarkers by LEfSe. Default is 10
--min_clade_size MIN_CLADE_SIZE
Set the minimum value of clades that are biomarkers.
Default is 20
--max_clade_size MAX_CLADE_SIZE
Set the maximum value of clades that are biomarkers.
Default is 200
--def_font_size DEF_FONT_SIZE
Set a default font size. Default is 10
--min_font_size MIN_FONT_SIZE
Set the minimum font size to use. Default is 8
--max_font_size MAX_FONT_SIZE
Set the maximum font size. Default is 12
--annotation_legend_font_size ANNOTATION_LEGEND_FONT_SIZE
Set the font size for the annotation legend. Default
is 10
--abundance_threshold ABUNDANCE_THRESHOLD
Set the minimun abundace value for a clade to be
annotated. Default is 20.0
--most_abundant MOST_ABUNDANT
When only lefse_input is provided, you can specify how
many clades highlight. Since the biomarkers are
missing, they will be chosen from the most abundant.
Default is 10
--least_biomarkers LEAST_BIOMARKERS
When only lefse_input is provided, you can specify the
minimum number of biomarkers to extract. The taxonomy
is parsed, and the level is choosen in order to have
at least the specified number of biomarkers. Default
is 3
--discard_otus If specified the OTU ids will be discarde from the
taxonmy. Default is True, i.e. keep OTUs IDs in
taxonomy
--internal_levels If specified sum-up from leaf to root the abundances
values. Default is False, i.e. do not sum-up
abundances on the internal nodes
--biomarkers2colors BIOMARKERS2COLORS
Mapping file that associates biomarkers to a specific
color... I'll define later the specific format of this
file!

--def_na DEF_NA Set the default value for missing values [default None
which means no replacement]

示例
examples文件夹包含以下子文件夹：hmp_aerobiosis、hmp_metahit_metabolic和{
#!bash
$ ./PIPELINE.sh
如果一切顺利，您应该在示例的同一文件夹中找到六个新文件：annot.txt，outimg.png，outimg_annot.png，outimg_legend.png，outtree.txt，和{
annot.txt：包含由export2生成的GraPhlAn将使用的注释graphlan.py脚本outimg.png：是GraPhlAn生成的循环树吗outimg_annot.png：包含循环树的注释图例outimg_legend.png：包含圆形树中突出显示的生物标记的图例outtree.txt：带注释的树是由graphlan生成的吗_批注.py在tree.txt：树是由export2生成的吗graphlan.py脚本
