Can't read input files: "list index out of range"

[kriskaykj]

Hello,

I am trying to compare two phylogenies on both the GUI and the CLI, but in both I get an error: "Error: cannot read host file path/to/file/host.nwk: list index out of range".

My host file looks like this: ((MT445.1_rc_rotated,((MN164.1_rc_rotated,MN164.1_rc_rotated),MN164.1_rc_rotated)),(((((MN164.1_rc_rotated,((Coci-NEP-7-notrim.,(((NeHi3-notrim.,NeHi4-notrim.),NeVoMP5-trim2.),(NeVoMP2-trim2.,NeVoMP3-trim2.))),ptg000021l_rc_rotated)),NeVoMP4-trim2.),(Coci-NEVO-2-trim2.,(NeVo4-trim2.,NeVo6-trim2.))),(NeVoKM2.,NeVoKM7-trim2.)),(((((NeHiPe6.,NeHiPe9.),NeHiPe7.),NeHiPe8.),(NeVoKD2-trim2.,(((NeVoKD3-trim2.,NeVoKD6-trim2.),(NeVoKD5.,NeVoKD7.)),NeVoKD4-trim2.))),(NeVoKD1_total_trim2.,NeVoKM8-trim2.))),KT874.1_rc_rotated);

I'm not sure what it is having an issue with. Thank you in advance!

i don;t know how to do

It looks like the developer has not been able to fix this bug as I am having the same issue...

Hello, I also had this error and I fixed it by deleting node labels in my tree file. I have a R code where I prepare the files before empress and I added this line to the code : host_tree$node.label <- NULL I hope this will solve your issue !

Ey, I'm having the same problem!, I founded that you probably need to collapse single tips in the tree (using ape). You could also add nodes labels to your trees (h=host, p=parasites), here is the way I solved it:

TreeH<-read.tree("Host_eMPR.nwk") # host tree TreeH<-makeNodeLabel(TreeH, method = "number", prefix = "h") #add nodes labels, here I used numbers and prefix "h", so h1 is node 1 and so on, and so on TreeH<-collapse.singles(TreeH) # collapse single tips ape::write.tree(TreeH, file='~/Desktop/eMPRess/host_nodes.txt') # exporting tree from R to my working directory (format is nwk, so you can change the extension later to .nwk or .tree)

Hope this help

Ey, I encountered the same issue. After reviewing the input files and comparing them with the example data provided, I found that the example data were all rooted trees, whereas my input files were unrooted trees. Once I converted my unrooted trees to rooted trees in R, the problem was resolved. rooted_tree <- root(unrooted_tree, outgroup = "Outgroup_Species", resolve.root = TRUE)
