Hi again,
I think a quadruple check is in order ;)
The extension of the file you sent is wrong. It is a .str.tsv file (?) while the correct extension should read .str. Seeing your command line, I suspect windows is hiding extensions by default on your computer, and so you are assuming there is a file called
C:/Users/Ella Bowles/Desktop/batch_1_8c9.str
where there is none - your file must be, in fact
C:/Users/Ella Bowles/Desktop/batch_1_8c9.str.tsv
After correcting the extension it all works for me:
> library(adegenet)
Loading required package: ade4
/// adegenet 2.0.1 is loaded ////////////
> overview: '?adegenet'
> tutorials/doc/questions: 'adegenetWeb()'
> bug reports/feature resquests: adegenetIssues()
> x=read.structure("batch_1_8c9.str", n.ind = 186, n.loc = 4099, onerowperind = FALSE, col.lab = 1, col.pop = 2, col.others = NULL, row.marknames = 2, NA.char = "0", ask = TRUE)
Which other optional columns should be read (press 'return' when done)? 1:
Converting data from a STRUCTURE .stru file to a genind object...
> x
/// GENIND OBJECT /////////
// 186 individuals; 4,099 loci; 8,198 alleles; size: 7.7 Mb
// Basic content
@tab: 186 x 8198 matrix of allele counts
@loc.n.all: number of alleles per locus (range: 2-2)
@loc.fac: locus factor for the 8198 columns of @tab
@all.names: list of allele names for each locus
@ploidy: ploidy of each individual (range: 2-2)
@type: codom
@call: read.structure(file = "batch_1_8c9.str", n.ind = 186, n.loc = 4099,
onerowperind = FALSE, col.lab = 1, col.pop = 2, col.others = NULL,
row.marknames = 2, NA.char = "0", ask = TRUE)
// Optional content
@pop: population of each individual (group size range: 12-20)
And yes, in case you wonder, window$ is an evil system and probably hates all of us.
Cheers
Thibaut

Hi Thibaut,
I checked, double and triple checked, and it is correct. Can you read it in?
I don't think this should be an issue, but the only thing that seems potentially amiss is that after I use the read.structure line R always asks for which other optional columns should be read. I just press enter here, so no other columns are read. Just seems weird that I would be getting a warning that looks like it should be for a filepath. Also, I'm running R v 3.2.2.
Will be good to know if you can read in the file.
Cheers
Thanks

Hi Thibaut,
I'm now using the line (all in one line)
data <- read.structure("C:/Users/Ella Bowles/Desktop/batch_1_8c9.str", n.ind = 186, n.loc = 4099, onerowperind = FALSE, col.lab = 1, col.pop = 2, col.others = NULL, row.marknames = 2, NA.char = "0", ask = TRUE)
for the attached dataset
and I'm still getting the error
Which other optional columns should be read (press 'return' when done)? 1:
Converting data from a STRUCTURE .stru file to a genind object...
Error in file(file, "r") : cannot open the connection
In addition: Warning message:
In file(file, "r") :
cannot open file 'C:/Users/Ella Bowles/Desktop/batch_1_8c9.str': No such file or directory
Can you see what may be wrong?
Thank you for your time,
Ella

Hi there,
please check the forum archives, this has been answered several times. I think I even mention it in the tutorial. You need to remove 'system.file' and just indicate the path to your file.
Cheers

Subject: [adegenet-forum] adegenet not recognizing file extensions
Hello,
I'm trying to read files into adegenet and convert to genind objects, but am getting an error. After I have correctly specified/set the directory that the files are in I have used the line
data <- read.genetix(system.file("8c9.gtx", package = "adegenet"))
for many different permutations of filetype. These include read.genepop for genepop files, read.structure for structure filies. I keep getting the error
Converting data from GENETIX to a genind object...
Error in if (toupper(.readExt(file)) != "GTX") stop("File extension .gtx expected") :
argument is of length zero
The thing that I can see as the possible issue is that my files originally had different extensions (from the populations program of stacks). They were previously ".genepop" and ".strucuture", and I changed them manually to the ".gen" and ".stru" suffixes. Can you see a way around this?
With thanks,
Ella
