I'm having problems with MI reshape which I've been unable to replicate in a public data set. My data has 20 sets of imputations.

My reshape command dies at the "assembling results" stage:

. mi reshape long adas12_m, i(studyid) j(month)

reshaping m=0 data ...
(note: j = 0 6 12 18)

Data                               wide   ->   long
-----------------------------------------------------------------------------
Number of obs.                       87   ->     348
Number of variables                  55   ->      53
j variable (4 values)                     ->   month
xij variables:
     adas12_m0 adas12_m6 ... adas12_m18   ->   adas12_m
-----------------------------------------------------------------------------

reshaping m=1 data ...

reshaping m=2 data ...

(snip)
reshaping m=20 data ...

assembling results ...
variable adas12_m not found
r(111);

I tried "noupdate" and also got an error message:

. mi reshape long adas12_m, i(studyid) j(month) noupdate

reshaping m=0 data ...
option noupdate not allowed
r(198);

Does anyone have any suggestions?  I may have to go directly to Stata.

thanks,

Laura
