The first error is probably the real issue:
Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec, :
line 1 did not have 4 elements
Calls: GetData -> read.file -> read.table -> scan
recover called non-interactively; frames dumped, use debugger() to view
Unfortunately it's not all that specific about which GetData() call is the problem. It does say line 1 did not have 4 elements
, and the LD file is supposed to have 4 columns, so perhaps that is where the problem is. I would recommend checking that file - make sure all columns have valid data, and that each row is whitespace delimited (not sure why "any whitespace" ended up as the delimiter for this file, but that's what it expects.)

Thank you for your response. D' values are not known, so I have an empty column with column header name dprime. According to the link you shared "The dprime column can be all missing if it is not known.". Should there be NA or some other values in the column then?
One question - is --refsnp rsSNP
in your command, or is rsSNP
replacing the real SNP ID for confidentiality?
The error message Warning: could not find position for SNP NA in user-supplied --ld file, skipping
makes me wonder if some or all of the SNP IDs are invalid (the SNP ID should not be NA
), or perhaps none of them could be matched with your --refsnp
ID.
rsSNP is replacing the real SNP ID (with an rs number) for confidentiality. Sorry about that. Some SNPs in my summary statistics file are coded likes this rs###,rs### or NA. I will remove these and run again. snp2 column contains only --refsnp ID. The LD file looks pretty clean, only rs numbers in snp1 and snp2 columns, empty dprimer column and valid r2 values in the 4th column.
Hi again. Just to clarify I am using version 1.4.
I cleaned both the summary statistics file and the LD file and rerun the script. Still getting similar error message.

Here is the header of my LD file, columns separated with single white space. dprime column has a header but is empty.

Do you think I should update the databases? I run this script on a cluster. I get error if I do not load R. I also make sure to "module load R" (v3.6.1) before I start this. And the python that locuszoom should see by default is Python 2.7.5.
Ahh, I think maybe I see the problem. The dprime
column cannot be empty, it must at least have some value (which could be all NA, if it does not exist.) It cannot be the empty string, because the delimiter is any whitespace (\s+), unfortunately.
Yes! That was the problem. Replacing blanks with NA in dprime solved the problem. Thank you again for your help.
Hello, I am trying to make some LocusZoom plots, using user supplied LD data. The summary statistics data is in --metal format and the program seems to recognize the LD file as well. After a long delay I started seeing around 66 lines that tells SNP is not found in the database, which I guess is expected.
Warning: could not find position for SNP NA in user-supplied --ld file, skipping. ... ...
At the end however, I get this error message and a white blank pdf file. I am hoping for some assistance. Thank you

Here is the command that I used
locuszoom --build hg19 --gene-table gencode --metal metal_file.txt --ld LDfile.txt --refsnp rsSNP --snpset NULL
