Hi,

There are some PLINK dosage files (format=1) that I need to convert to bed/bim/fam (using best guesses of genotypes). Namely, the .dose files I have are like:

SNP    A1    A2    F1 I1    F2 I2    ...
rsXXX    A    T    1.692    1.699    ...
...

If I understand well (http://www.bx.psu.edu/~giardine/tests/tmp/fcgene-1.0.7.pdf, p.10), I could re-format them by using:

./fcgene --dosage file.dose --fam file.fam --map file.map --oformat plink-bed

However, I get this error:

ERROR: First line of plink dosage format file "file.dose" should start with the word "SNP", the second column with the word "A1" and the third column with the word "A2".

I have tried changing tabs for single spaces in "file.dose", but still I get the same message. Do you know how to fix it?

Thanks in advance,

Same problem, even with the example files provided in v1.0.6 EROOR: First line of plink dosage format file "work_examples/plink/plink_dosage.dose" should start with the word "SNP", the second column with the word "A1" and the thrid column with the word "A2"

How did you compile your dosage file? Did you enter the data or the header manually? Could it be that you have "hidden" symbols or characters in there so that PLINK cannot read the first line correctly?

Has anyone figured out the answer to this problem? I am having the same issue.

Thanks

Just use plink 2.0 —import-dosage + —make-bed.
