Problem with chimera model

[Tony Pemberton <pemberaj AT sgisw.bham.ac.uk>]

Dear Users,

I am trying to produce a chimeric model as in FAQ number 4.
However I am getting the following error using Modeller release 4:-

>> CHECK_ALIGNMENT: 

chkaln___> Checking pairwise structural superpositions: 
           Equivalent CA pairs with distance difference larger than 6.0
angstroms: 

ALN_POS TMPL1 TMPL2 RID1 RID2 NAM1 NAM2 DIST
----------------------------------------------------

chkaln___> Checking structure-sequence alignments: 
           Implied target CA(i)-CA(i+1) distances longer than 8.0
angstroms: 

ALN_POS TMPL RID1 RID2 NAM1 NAM2 DIST
----------------------------------------------

<< end of CHECK_ALIGNMENT. 

fit2xyz_E> number of equivalent positions < 3:  2
recover__> MODELLER_STATUS >= STOP_ON_ERROR:  1 1

Can someone tell what this error means,

Regards,

Tony Pemberton
