R language ggtree how to change the sequence id in the evolutionary tree into species names, many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can get something.

Usually we use the matched fasta file to build the evolutionary tree, and the content after the greater than sign in the fasta file is the text tag on the final evolutionary tree. What if you want to replace some of the contents of the evolutionary tree file after you get it? This tweet introduces the use of ggtree packages in R language to achieve this purpose.

This question comes from a reader of the official account.

You can follow my official account Xiao Ming's data analysis notebook message related problems, if I happen to know it, I will take the time to introduce the corresponding solutions.

First of all, you already have the constructed phylogenetic tree file (Synergus:0.1976902387, (Periclistus:0.1403183720,Synophromorpha:0.0325185390) 93V 0.0313182375, (Xestophanes:0.0275715134, (Diastrophus:0.0456139475,Gonaspis:0.1146402107) 97V 0.0603746476) 86V 0.0275523221) 91v 0.0396704245M IbaliaVOR 0.1295291852) 93Rd 0.0678466304, ((Liposthenes_ker:0.0568838340,Rhodus:0.4243267334) 73Rl 0.0825510697Part PlagiotrochusRu 0.0778290252) 71Rd 0.0457931797 Phanacis_2:0.1416544135) 42 Antistrophus:0.1098867540,Hedickiana:0.2313789580 0.0142517743) 4815 0.0209026386, ((Liposthenes_gle:0.1641119081, (Antistrophus:0.1098867540,Hedickiana:0.2313789580) 73mer 0.0566918206) ()) 73)) 0.0566918206) 53 (0.1747090949) 53) 0.0027850349, (Isocolus:0.0980216531,Aulacidea:0.1315344980) 40 (0.0147148853) 54 (0.0123010924, ((Andricus:0.0479556214,Neuroterus:0.0392025403) 95) 0.0395094917 Biorhiza:0.0640188941) 87Ru 0.0159496082) 20Rd 0.0000025961) 50Rd 0.0194234721, (Panteliella:0.0792235900,Diplolepis:0.3184402599) 84V) 0.0461941800) Phanaciseal 1Rover 0.1153410113) 660.009999961323, (Eschatocerus:0.2548694740,Parnips:0.0000022831) 64RV 0.0802390069) 34Rd 0.0241704495, ((Barbotinia:0.0731026287,Aylax:0.0957869567) 87Rod 0.026993277 frontier Iraellarel 0.0390833327) 95Jet 0.0797807340) 180.0000021284) 2324262646 Timaspis:0.0585073936) 19 Pediaspis:0.1932340906,Paramblynotus:0.1711455809 0.0170106400) 57 Pediaspis:0.1932340906,Paramblynotus:0.1711455809 0.0526944283, (Ceroptres:0.1057541047, (170106400) 28150000021043) 481416999011)
