Error when Causal Analysis using Mendelian randomization

When I tried the sample in the Casual Analysis using MetaboAnalyst 6.0, the same metabolite of Cystathionine and the same repository finn-b-E4_DM2 were used. But it always give an error warning.

Hi,
I cannot reproduce this issue. Can you please try it again or give us more details?

Thanks,

Zhiqiang

I tried again, now everything is fine. Maybe the server issue previously. Thanks.
