An individual with Sarmatian-related ancestry in Roman Britain

[Capsian20]

Thanks you i was trying to do a this sample G25_K13 but isnt work ( This does not appear to be a valid 23andME DNA file)

Which one did you try? Sarmat01 or Sarmat_QC ?  What type of file format is used by your software? Geno,  23andME or plink (bed,bim, fam) ?

 Sarmat_QC  , i converted bim to txt

 Sarmat_QC  , i converted bim to txt

Try to readjust the settings in .fam file:

1 data_3.b 0 0 0 1
2 data_4.b 0 0 0 1
3 data_5.b 0 0 0 1

.fam (PLINK sample information file)
Sample information file accompanying a .bed binary genotype table. (--make-just-fam can be used to update just this file.) Also generated by "--recode lgen" and "--recode rlist".

A text file with no header line, and one line per sample with the following six fields:

Family ID ('FID')
Within-family ID ('IID'; cannot be '0')
Within-family ID of father ('0' if father isn't in dataset)
Within-family ID of mother ('0' if mother isn't in dataset)
Sex code ('1' = male, '2' = female, '0' = unknown)
Phenotype value ('1' = control, '2' = case, '-9'/'0'/non-numeric = missing data if case/control)

Some software may ignore the samples without sex or if other missing info. May be the last column for  Phenotype value .

I dont know how i use it but anyway thanks you

Thanks to a discussion with Capsian,  I was able to generate G25 for this Roman Sarmatian.
I am not a big fan of G25, but for those who like to check further:

Let see if these results make sense .
