RE: MAXIDS=10000

Brian,
 
You can only submit posts to nmusers from the email address you are
subscribed from (it eliminates spam for those not registered). Your
file was distributed via the list at 7:41pm last night.
 
The SIZES file contains the formulas for changing values within
commented lines of the file. For example:
 
C LPAR: MAX. NO. OF PARAMETERS THAT MAY BE ESTIMATED
      PARAMETER (LPAR=70)
C LPAR2: I*(I+1)/2 WHERE I=SQRT(FLOAT(2*LPAR))
      PARAMETER (LPAR2=66)
 
So, if you change the value of LPAR from 70 to 100, you need to
calculate LPAR2 based on the formula: I*(I+1)/2 WHERE
I=SQRT(FLOAT(2*LPAR))
 
C LPAR: MAX. NO. OF PARAMETERS THAT MAY BE ESTIMATED
      PARAMETER (LPAR=100)
C LPAR2: I*(I+1)/2 WHERE I=SQRT(FLOAT(2*LPAR))
      PARAMETER (LPAR2=105)
 
However, if you search the SIZES file, you will find that none of the
buffers or other parameters has a formula indicating dependence on
MAXIDS. So, theoretically at least, you should need no other changes
before you recompile NONMEM. If you recompile and your run gives you an
error message regarding LIM6 or any other buffer, you may need to
increase the size of the specific buffer indicated by the error message
making the value incrementally larger until the error message goes away.

Hi Bill,
 
I submitted the letter below to nmusers last night but haven't yet seen
it distributed to the nmusers list.
 
I believe I am registered at nmuser through my yale address. Would it
have been better to give my gsk address, which is
brian.j.mchugh

It is elementary to determine how to set the MAXIDS value, but how does
one determine how to set the buffer values?
 
Best Regards,
Brian

Dear NMUSERS,

The following two lines reside in the SIZES file of NONMEM_6.2.0:

C MAXIDS: MAX. NO. OF INDIVIDUALS IN DATA SET
      PARAMETER (MAXIDS=10000)

If the numbers of ids exceeds 10,000, I've read Tom Ludden of Icon
Development Solutions recommend that users may want to adjust "this"
value, "the value for LIM6" and "any other parameter values in SIZES" to
meet their specific needs.

I have a dataset with greater than 10,000 Individuals, which means I
will change MAXIDS. Since it was mentioned that LIM6 also needs to be
changed (is this dependendent on the number of IDs?), does anyone know
if any other parameters, e.g., LIM1, LIM2, LIM3, LIM4, LIM5, LIM7, LIM8,
LIM 11, LIM13, LIM15, or LIM16, might need to be changed to satisfy my
needs before I recompile NONMEM?

Kind Regards,
Brian
