Dear Grace,

I would need to use your dataset to reproduce the error.

Is there a way for me to send it to you privately? Thanks

Hi Guangyan.
I used a different dataset. Similar problem appeared. This time it says “peak processing failed at structure propagation step”. Please help.
Thanks,
Grace

Hey Grace,

The issue comes from the fact that you only uploaded a list of significant peaks but you need to upload the whole list (usually 10k), including those that have p-value more than 0.05.
