Re: error

Hi Andrzej,

your input contains a few mistakes on the cards
* heavyion
LAM-BIAS WHAT(3) = 0. 5 (there is a space between the 0. and the 5)
* for muon production
PHOTONUC contains as material -2
* USRYIELD cards if you want logarithmic on the first quantity (ie) then
the ie should be negative not the ia therefore the ie=-1 and ia=14
WHAT(1) = 1399

and finally your problem of the RESNUCLEi cards is because you have not
set the WHAT(4), therefore the maximum neutron excess, of the scoring is
based on your material COPPER and not on your projectile U-238. To
correctly set it please refer to the manual notes 2&3
          2) To minimise storage, nuclei are indexed by Z (with Z_min =
1) and
             NMZ = N - Z (with (NMZ)_min = -5). The parameter M is
defined as
             M = NMZ - (NMZ)_min: therefore M_min = 1. The following
relations
             can also be useful:
                N - Z = M + (NMZ)_min N = M + Z + (NMZ)_min

          3) In the case of heavy ion projectiles the default NMZ, based
             on the region material, is not necessarily sufficient to
score all
             the residual nuclei, which could include possible ion
fragments.

I would recommend for this things to check your input with flair. Most
of these errors are highlighted.

Cheers
Vasilis
