Error in svd(X) : infinite or missing values in 'x' #47
Comments
Duplicate of #34 |
This error may happen when there are missing values in your genotype, which would cause problem when implementing Eigen decomposition on genomic relationship matrix, but looking at the printed log information, the Eigen and GLM accomplished without error, thus it seems to be more likely attributable to the variance components estimation in MLM. I firstly suggest you to check the genotype to see if there are any missing in your genotype. If not, then have a try to change another variance estimation algorithm (eg, |

Could you please check if there is any missing value in the genotype data? |
Dear Dr. xiaolei,
There are missing value in genotype in that case what should I do? How to
deal with it?
Sincerely,

Please impute the genotype data first, there are a lot of imputation tools, e. g., beagle, minimac. If there is only a few missing values in genotype matrix, you can use MVP.Data to convert your genotype data and the missing genotype will be imputed by the major allele. |
But if there are many missing values then what to do ? As it is 130K genotype data. Total Missing is about 1045847 out of 130K SNPS. |
Dear Dr. Xiaolei, |
As FarmCPU incorporated pseudo QTNs selected from the genotype data, so it needs a fully imputed genotype data. Therefore, you have to impute the genotype data regardless of any software you will use. |
Thank you for the information. The beagle I tried out but its not getting downloaded and secondly minimac also having some issues. Can you please suggest the software where I can submit the CSV. or Excel file of genotype data for imputation? |
I am not sure if there is any software that can accept the genotype in csv or excel format. You may try TASSEL, which can accept the hapmap file and also has the imputation function. |
This issue is closed because it is no longer active. |
Hi,
I was able to run but due to huge size GBS data. It got hanged on windows
based R script. Do you have script to perform In Linux?
Thanks & Regards

Hi,
You can use the same script to analyze your data in Linux.
