为什么写这个文章,其实是自己在安装和运行的过程中遇到了两个关于软件安装版本的问题,和一个路径问题(1)软件安装的版本不是最新的。(2)安装上新版本了,但是内部涵盖的软件本身的版本过于落后,导致调用不成功。路径问题是使用hmmer 比对的时候,按照之前网上的教程,路径一直报错。
安装eggnog-mapper的本地版
根据官方的指导教程,目前有三种方法去安装软件,我首选的是使用conda去安装软件,因为这是常见的最省心和最快的方法
conda create -n testemapperinstall python=3.7
conda activate testemapperinstall
conda install -c bioconda eggnog-mapper
会提示需要安装如下的包

但是这里踩了一个坑,使用conda安装的版本eggnog-mapper 的版本并不是最新的2.1.10,而是2.1.3,在通过指定版本安装conda install -c bioconda eggnog-mapper=2.1.10
的情况下依然安装不上最新的版本。并且使用conda安装的diamond version是 0.9.24,是不符合eggnog-mapper需要的版本的,后面如果使用diamond进行比对会一直报错Error running diamond: Error: Invalid option: iterate
。
所以只能采用使用 pip install
的方式去安装,然后检查安装文件可以看到已经安装成功了,并且diamond的版本也是正确的Diamond version found: diamond version 2.0.11
conda create -n testemapperinstall python=3.7
conda activate testemapperinstall
(testemapperinstall) user@vm-9c70-cfc9f5802384:~$ pip install eggnog-mapper
(testemapperinstall) user@vm-9c70-cfc9f5802384:~$ emapper.py --version
There was an error retrieving eggnog-mapper DB data: not a valid file "/home/data/t040403/miniconda3/envs/testemapperinstall/lib/python3.7/site-packages/data/eggnog.db"
Maybe you need to run download_eggnog_data.py
emapper-2.1.10 / Expected eggNOG DB version: 5.0.2 / Installed eggNOG DB version: unknown / Diamond version found: diamond version 2.0.11 / MMseqs2 version found: 113e3212c137d026e297c7540e1fcd039f6812b1
前期准备
下载eggnog注释文件
目前数据库提供非常多的datasets,如果只需要基础注释,那么直接运行下载脚本就可以了,如果想使用hmmer针对特定的datasets进行注释,需要下载相应的taxID的datasets。
Diamond DB是可选的。我们也可以决定执行HMMER或MMseqs2搜索,也可以创建特定于某个分类范围的Diamond或MMseqs2 DB。为此,可以使用download_eggnog_data.py——help(用于下载HMMER数据库或整个Diamond或MMseqs2数据库),并检查create_db .py——help(用于创建特定于分类的Diamond/MMseqs2数据库)。此外,可以下载PFAM数据库,以便能够使用——pfam_realign realign或——pfam_realign denovo以运行PFAM realignemts
# 针对基础注释下载数据
# 这将下载eggNOG注释数据库(以及分类库数据库)和用于Diamond搜索的eggNOG蛋白质数据库。
python download_eggnog_data.py
# 针对有hmmer需求的注释,以昆虫为例
python download_eggnog_data.py -P -H -d 50557
# 查看其它的参数
download_eggnog_data.py -h
``` shell
## 开始进行注释
### 基础注释
目前从v2.1.5-2.1.10的版本,默认的注释方式使用的是`diamond blastp`,而不是之前的hmmer,目前网上的其他教程使用的默认的注释方式还是基于hmmer的,而不是diamond的。用diamond的好处就是很快。
nohup emapper.py -i myprotein.fa -o test_diamond --cpu 60 > diamondtest.out 2>&1 &
会生成4个文件
diamondtest.out
test_diamond.emapper.annotations
test_diamond.emapper.hits
test_diamond.emapper.seed_orthologs
查看.out文件中运行的时间
Total hits processed: 13334
Total time: 1155 secs
diamond的速度还是比较快的,基本输入17000+的序列,20分钟左右就给出了结果
**但是如果在NCBI上近缘物种收录比较少的物种,选择diamond比对的注释率通常会比较低,这类物种最好使用hmmer比对。比如昆虫,可能做你这种虫子的实验室也就没有几家,并且也没有很好的基因组注释,那么,也就是本文非常实用的方式,自己下载一个本地版的eggnog-mapper进行比对,使用网页版的eggnong进行比对,也不会提供使用hmmer比对的选项。**
## 使用hmmer进行注释
hmmer注释有两个参数 `-i`和`-d`是必须要给出的,`-d`针对的就是我们之前下载好的物种的taxID。hmmer的比对一般需要的时间比较长,基本跑上了以后过夜孵育就行了。
***按照之前刘永鑫和徐洲更两位大佬写的教程(当时版本的eggnog还是以hmmer作为默认的比对方式,而不是diamond),-d需要指定到文件夹下面的.hmm文件的位置,但是目前最新的版本只需要指定到taxID就可以了,否则一直会报错 `Could not find ./hmmer/50557/50557.hmm among eggnog databases. Skipping seed ortholog detection.Could not find hits to annotate.`,只会生成最后的一个.hits文件,并不会生成annotation文件。***
```shell
nohup emapper.py -i myprotein.fa -m hmmer --output anno_hmm1 -d 50557 --num_servers 60 --cpu 60 --override > test_hmm1.out 2>&1 &
#同样生成4个文件
test_hmm1.out
anno_hmm1.emapper.annotations
anno_hmm1.emapper.hits
anno_hmm1.emapper.seed_orthologs
两种方式的比较
查看两个文件分别有多少条序列被注释上了
grep queries test_diamond.emapper.annotations
## 13334 queries scanned
grep queries test_hmm1.emapper.annotations
## 13870 queries scanned
我们可以看出来hmmer的结果从数量上来说是要多一点的:
diamond的比对结果
13334 queries scanned
hmmer的比对结果
13870 queries scanned
结果查看
其实我们需要的文件是.annotation结尾的文件,这个文件中含有KEGG 和GO富集分析需要的GO号和KO号,还有每个基因对应的kegg map号等。这也是我认为使用eggnog最方便的地方,可以方便的获得基因和对应的通路的关系*有了这些对应关系,可以构建自己物种的orgdb,这样我们就可以很轻松的调用clusterprofiler包进行富集分析,这对于做湿实验的同学们来说实在是太友好了。
关于怎么调用R包进行分析,网上的教程很多,可以通过本地的代码实现,也可以通过CJ大神开发的TBTOOLS进行点点点的操作实现。
