[HLA_Imputation_BEAGLE5.py::ERROR]: Imputation(exon2 / overlap:0.5) failed.

Hello @WansonChoi I am facing error in the last step of CookHLA pipeline, I used my data (chr6 29mb-34mb) data with the reference data from 1000 genome reference panel however it failed due to the following error [4] Performing HLA imputation(exon2 / overlap:0.5).

[HLA_Imputation_BEAGLE5.py::ERROR]: Imputation(exon2 / overlap:0.5) failed.

During handling of the above exception, another exception occurred:

Can you please guide me to solve this issue

@Aamiralizai

Hi, Aamiralizai,

Thank you for your interest in CookHLA.

Could try the imputation with Beagle 4 instead of 5? (with the '-bgl4' argument.)

If it fails again, then please attach the log files of the failed imputations. (ex. "MyHLAImputation/data1+1000G_REF.EAS.MHC.QC.exon2.0.5.raw_imputation_out.log")

@WansonChoi Thank you for your response, the problem was in my .fam file.

Hi @Aamiralizai ,

The same error came up in my running. Could you please tell me what had happened in your .fam file?

I will be very grateful if you can reply.

Thank you very much! Guo

Hi @Xingejun, You can have a look to at any reference .fam file and compared with you .fam file if there is any difference in the FID and IID, In my case the the error was due to FID and IID in my .fam file.

Hi @Aamiralizai ,

Thanks. My issue had been solved and it is not in the .fam. Actually I didn't figure out what happened.

Hi @xingejun, I am encountering a similar problem. Can you share how you solved the problem?

[Aamiralizai]

@PoojaMiddha try --beagle4 instead of beagle5

Hi @PoojaMiddha ,

I have met a lot of problems at that time when I was trying running it. And a lot of solutions I have tried so I can't sure which one works. I thought it mostly likely because I changed my running environment suitbale for java or memory set.
