Hi everyone,

I import a RAxML tree file into the RStudio in the Galaxy.

1. When I used the code: ```  
tree ← read.tree(treefile)

```auto
An error reported as: Warning message:
In read.tree(treefile) : no semicolon(s) [end(s) of tree] found

2. When I used the code:
 tree <- read.tree(file = "", text = NULL, tree.names = NULL, skip = 0, comment.char = "", keep.multi = FALSE)
In the console panel, that will appear a number like the screenshot as following.
![1737615805(1)|690x334](upload://aKMw1TFKCZFL18K9iKLEAh71B3x.png)

Can anyone help me?

Thank you.
```

Hi Jane,

I have never used this tool before but in the error message it says that your file does not end with a semicolon “;”. I read [here](https://cran.r-project.org/web/packages/TreeTools/vignettes/load-trees.html) that to use `read.tree` your files should end with a semicolon. You can use a text editor to add a semicolon to the end of your file.

Best regards,
