interproscan
interproscan 是个基因注释工具,可以一次运行实现多个数据库的注释。用户既可以提交蛋白序列也可以提交核酸序列,还可以对输出格式进行设置。
具体支持的数据库有:
下面这些分析虽然也能用 interproscan 来进行,但许可代码(licensed code)和数据(data)是由第三方提供的,需要自己下载并配置:
安装要求
- 64-bit Linux
- Perl 5 (default on most Linux distributions)
- Python 3 (InterProScan 5.30-69.0 onwards)
- Java JDK/JRE version 11 (InterProScan 5.37-76.0 onwards)
- Environment variables set
$JAVA_HOME should point to the location of the JVM
$JAVA_HOME/bin should be added to the $PATH
具体如何配置安装环境查看官方文档。
下载安装 interproscan
mkdir my_interproscan
cd my_interproscan
wget ftp://ftp.ebi.ac.uk/pub/software/unix/iprscan/5/5.45-80.0/interproscan-5.45-80.0-64-bit.tar.gz
wget ftp://ftp.ebi.ac.uk/pub/software/unix/iprscan/5/5.45-80.0/interproscan-5.45-80.0-64-bit.tar.gz.md5
# 推荐用md5sum检查下载是否成功
md5sum -c interproscan-5.45-80.0-64-bit.tar.gz.md5
# Must return *interproscan-5.45-80.0-64-bit.tar.gz: OK*
# If not - try downloading the file again as it may be a corrupted copy.
tar -pxzf interproscan-5.45-80.0-64-bit.tar.gz
# where:
# p = preserve the file permissions
# x = extract files from an archive
# z = filter the archive through gzip
# f = use archive file
下载 Panther Models
可以用来做 Panther member database analysis,具体看分析需求,可下可不下。
安装前需先将 interproscan 下载并安装好,需要在 interproscan 所在的文件夹内创建 data 文件夹,并将其下载解压在该文件夹。
cd [InterProScan5 home]/data/
wget ftp://ftp.ebi.ac.uk/pub/software/unix/iprscan/5/data/panther-data-14.1.tar.gz
wget ftp://ftp.ebi.ac.uk/pub/software/unix/iprscan/5/data/panther-data-14.1.tar.gz.md5
md5sum -c panther-data-14.1.tar.gz.md5
# This must return *panther-data-14.1.tar.gz: OK*
# If not - try downloading the file again as it may be a corrupted copy.
tar -pxvzf panther-data-14.1.tar.gz
使用 Local Pre-calculated Match Lookup Service (Optional)
通过提交序列在线比对来加快注释速度,需要电脑能连接 http://www.ebi.ac.uk
也可以下载到本地 download and install the InterProScan 5 lookup service,
或者直接关闭这个服务,这样分析就只会本地进行。
在分析时添加 -dp 参数或直接在interproscan.properties中注释掉即可
#precalculated.match.lookup.service.url=https://www.ebi.ac.uk/interpro/match-lookup
使用 interproscan
# 查看用法
./interproscan.sh
# 测试运行,结果应该会个生成两个文件
./interproscan.sh -i test_proteins.fasta -f tsv
./interproscan.sh -i test_proteins.fasta -f tsv -dp
输入格式
fasta 格式的蛋白或核酸序列,序列中不能含有 ·
-
或 *
等非法字符。
输出格式
- TSV: A simple tab-delimited file format
- XML: The "IMPACT" XML format (XSD available here).
- JSON: Full output of results in JSON format
- GFF3: The GFF 3.0 format
- HTML: An HTML representation of the protein matches
- SVG: An Scalable Vector Graphics representation of the protein matches
