Hi Alice,

Thanks for your email.  This is a bug, which should be fixed in beadarray
1.7.4.  Most arrays we see (those from SAMs and WG6 chips) are named using
the convention chipID_row_column, and this information is stored along with
other processing options in the arrayInfo slot of a BeadLevelList.  Your
arrays look to be named as chipID_row, and when readIllumina() attempts to
store something for column, you get the error below.  I guess this naming
convention is used for human/mouse 8 arrays?

Best wishes,

Matt
