Hi,
I'm new here and found your project interesting and helpful!
But I'm kinda confused about the lefse output for the single feature produced by lefse-plot_features.py. Cuz there is no subclass(SampleID) annotation under the Fig. yield, like your own example result showed:
only group classification above the bars.
Is it because the input file doesn't include the subclass(SampleID) information? If so, then how should I insert that info into input file? by format2lefse? I failed to modify format2lefse Rscript to make it. Can you help me with this?
您好,在运行单样本使用humann3时可以正常运行,使用rush多任务时报错,请问如何解决
tail -n+2 result/metadata.txt | cut -f1 | rush -j 2
"humann --input temp/concat/{1}.fq
--output temp/humann3/ --threads 3 --metaphlan-options '--bowtie2db /db/metaphlan4 --index mpa_vOct22_CHOCOPhlAnSGB_202212 --offline'"
报错如下:
(humann3) xumingyuan@cn5:meta$tail -n+2 result/metadata.txt|cut -f1|rush -j 2 \
"humann --input temp/concat/${i}.fq --output temp/humann3/ --threads 32 -- metaphlan-options '--bowtie2db /home/xumingyuan/data_HD/database/metaphlan4 --index mpa_vOct22_CHOCOPhlAnSGB_202212 --offline'"
/bin/bash: line 1: humann: command not found
/bin/bash: line 1: humann: command not found
[ERRO]
我修改补全了humann3的地址,tail -n+2 result/metadata.txt|cut -f1|rush -j 2
"/home/xumingyuan/data_HD/micromamba/envs/humann3/bin/humann --input temp/concat/${i}.fq --output temp/humann3/ --threads 32 -- metaphlan-options '--bowtie2db /home/xumingyuan/data_HD/database/metaphlan4 --index mpa_vOct22_CHOCOPhlAnSGB_202212 --offline'"
humann: error: unrecognized arguments: -- metaphlan-options --bowtie2db /home/xumingyuan/data_HD/database/metaphlan4 --index mpa_vOct22_CHOCOPhlAnSGB_202212 --offline
[ERRO] 。
非常感谢。

您好!本人生信小白一枚,最近在按照0install.sh安装软件配置环境,在运行NCBI核酸和物种信息(可选)部分时遇见了解压数据库的问题。由于最近国家微生物科学数据中心网页维护,我从网盘中下载了NCBI/nt中的所有*.tar.gz安装包,并成功上传到我的服务器。运行cd ${db}/NCBI/nt; for i in *.tar.gz; do tar xzf $i; done对安装包逐个解压时,压缩包01 08 09 25 26 35 48 59 61 65 70出现了报错。有以下两个报错:
tar: 跳转到下一个头
gzip: stdin: invalid compressed data--crc error
gzip: stdin: invalid compressed data--length error
tar: Child returned status 1
tar: Error is not recoverable: exiting now
gzip: stdin: invalid compressed data--format violated
tar: 归档文件中异常的EOF
tar: Error is not recoverable: exiting now
按照脚本中提示和网络检索的帮助,我认为文件可能有损坏,于是重新在云盘上下载。重新上传后问题1解决,但问题2无法解决,想要寻求帮助。
另外,看到教程中NCBI核酸和物种信息为可选,我是否可以直接跳过这一部分?
感谢感谢
老师您好!
您的代码中吗,使用megahit组装的时候,都是基于所有样本进行拼接的,但是若实操的时候,面临大样本数据,计算机内存不足以进行混合组装,只能使用单样本组装后,如何进行后续去冗余,基因定量,功能注释等步骤呢。是单样本组装后,将所有样本分别组装后的contigs,cat汇总成一个大contig文件,在进行后续去冗余等步骤吗?希望老师能解答我的问题,十分感谢!
刘老师,流程中提到了Script目录,但是在项目文件里面我没找到,我应该如何获取?这个Script目录是保密的?我应该如何获取?谢谢!
作者您好!我想请问一下*EasyMicrobiome/dbcan2/CAZyDB.08062022数据库在哪里呢?我没有找到。
如果使用以下方法下载的数据库是否是一致的呢?
访问CAZy官网:[https://www.cazy.org/;](https://www.cazy.org/%EF%BC%9B)
点击页面上方的“Download”按钮,进入下载页面;
在下载页面中,找到CAZy Database一栏,点击右侧的Download链接;
进入CAZy Database下载页面后,选择与您的系统版本相对应的文件进行下载,例如Linux系统可以下载cazy_2022-08-06.tar.gz文件;
解压文件:tar zxvf cazy_2022-08-06.tar.gz;
将解压后的文件放到您需要使用的位置。
老师好,我们能提供在集群上运行的snakemanke版本吗?
Hi Ph.D. Liu,
I am puzzled with the part that how to select a fixed number of reads across all samples in the metagenomic analysis. Is there any software or script that is fittable to humann2 pipeline?
Thank you!
按照 1.Pipeline 里的代码用Bracken重新估算 C1和C2的丰度,但是汇总结果文件时发现,结果文件的行数并不相同。但是Kraken2的结果行数是相同的 ,按照1.Pipeline里的代码可以直接进行合并。下面是bracken的参数-r 100 -l S。
bracken -d ${kraken2_db} -i
-r ${len} -l ${tax} -o
-w
请问造成这种结果的原因是什么?这样的结果是否有问题?
