首先查看一下gff文件和CDS文件的对应情况，有的gff文件没有transcript_id这个注释。
比如我的就没有
python -m jcvi.formats.gff bed --type=mRNA --key=Name T_ant_maker.final.gff > T.bed
python -m jcvi.formats.gff bed --type=mRNA --key=Name A_aqu_genome.final.gff > A.bed
···
如果没有CDS文件，就自己提取
gffread in.gff3 -g ref.fa -x cds.fa
···
python -m jcvi.formats.fasta format --sep="|" T_ant_cds.fa T.cds
python -m jcvi.formats.fasta format --sep="|" A_aQU_cds.fa A.cds
python -m jcvi.compara.catalog ortholog T A --cscore=.99（画个点图看看共线性）
python -m jcvi.compara.synteny screen --minspan=30 --simple T.A.anchors T.A.anchors.new
或者不加参数：python -m jcvi.compara.synteny screen --simple T.A.anchors T.A.anchors.new
python /home/spider/project/yuantao/script/hoptop_scripts/simple2links.py T.A.anchors.simple
python /home/spider/project/yuantao/script/simple2links.py A.T.anchors.simple
T.A.anchors.simple_link.txt文件就可因用来画圈图了，你也可以把里面每个染色体的共线性区块保存成一个文件，后面画不同的颜色。
类似上图1号染色体的复制粘贴放一个文件，2号染色体的复制粘贴放一个文件，以此类推。
circos.conf文件，每个染色体区块单独设置颜色。
