Hi everyone,
This is my first post so I apologize if its not great, any advice on posting etiquette is valued highly!
I am attempting to use smartpca from Eigensoft to perform a PCA with a subset of genotyped individuals and then project another individual onto the plot. I followed the instructions in the README file and made a list of population names and added the poplistname parameter to my par file:
genotypename: PI.merged.ped
snpname: PI4.merged.map
indivname: PI.merged.ped
evecoutname: PI.merged.evec
evaloutname: PI4.merged.eval
numoutlieriter: 0
poplistname: PI.poplist.txt
However, I keep getting this error message everytime I try to run the program:
"fatalx:
XTX has zero trace (perhaps no data)
Aborted (Core dumped)"
I tried using different formats in the par file but nothing fixed the issue.
Does anyone have any advice regarding what I may be doing wrong?
Many thanks!
