[Genome] Bemused by an "invalid signed number" error in liftOver

[Melissa Cline]

Hi,

I was trying to use the liftOver utility to translate some mm9 coordinates
to mm8.  I got an error on the following line:

chr10   102471840       102471903       Homeo_OAR(PF03826)
2.1e-09-       102471840       102471903       0       1       63
0
(note that all fields should be tab-delimited, whether or not the tabs have
been preserved as tabs).

When I enter this line into the "Paste in data:" field on the Lift Genome
Annotations form, I get the following response:

invalid signed number: "2.1e-09"


Why is this number invalid?  The BED file documentation says that the score
field should contain a number between 0 and 1000, which it is, so I'm
honestly unclear on what's wrong.  What do I need to do to fix this?

Thanks,

Melissa
