at the beginning of the "realign" I got the following warning message:

- Requested axes limit range too small; rendering with minimum range allowed by machine precision
in     spm_chi2_plot.m at line 65
        spm_realign.m (realign_series) at line 793
        spm_realign.m (realign_images) at line 661
        spm_realign.m at line 372

and then, the registration goes on without problems.

What does it mean?
Are the images correctly registered?

Thanks in advance
Fabiana
