ZOE ERROR (from forge): zoeNewFeature illegal feature

[HaoGuo0]

When I use the following methods:

**

cat uni.ann wrn.ann > glue.ann
cat uni.dna wrn.dna > glue.dna
fathom -export 1000 -plus glue.ann glue.dna
forge export.ann export.dna
**
The following errors will occur:

**

ZOE WARNING (from forge): zoeVerifyFeature: coordinate not positive
ZOE WARNING (from forge): zoeVerifyFeature: undefined coordinates
Acceptor 0 0 + . . . .
ZOE ERROR (from forge): zoeNewFeature illegal feature
ZOE library version 2017-03-01
**

But without merging uni and wrn, when running uni alone, this error will not occur and will run normally.
So the problem should occur in WRN, so I would like to ask what kind of data in WRN would cause this problem to occur.

Thank you very much for your answer.
