1) using bioconda: conda install -c bioconda seqtk, 2) using brew on a MAC: brew install seqtk, and 3) source code: obtain source code from the GitHub repository and compile it.The following examples explains how to use seqtk subseq to extract the sequences from FASTA/FASTQ files....

Troubleshooting Tip: The sequence name in the BED file’s first column should exactly match the sequence name in the reference FASTA file. The BED file should be TAB separated. FASTA and BED files should have a Unix line break (use thedos2unixcommand). Similarly, you can also useseqtk sub...
FeatureExtract--extracts sequences and feature annotation from genbank format file 最近一直在看和植物叶绿体基因组有关的知识,其中有一项内容是分析叶绿体基因组的密码子偏向性,这就要求我们首先要拿到基因的CDS序列,在NCBI的organelle genome数据库中我们通常可以下载到叶绿体全基因组的fasta文件,genbank文件;gff3...
