undesirable behavior in PrediXcan.r script

[Takahiro0113]

Thanks for your great work !!
I have encountered a small undesirable behavior in --generate_db_and_cov mode in PrediXcan.r.
When SNPs of eff_allele column in weight file are all "T", it seems to be recognized as logical "TRUE" instead of character. It ends up with characters "TRUE" in eff_allele column in .db file.
I guess that this problem could occur with JTI because JTI tends to use fewer SNPs than PrediXcan for prediction.

Best regards,
Takahiro
