Hell Britt，
      Thank you very much for your reply!
       I add the formatting comments to my data file before the reflection lines, but it hints:
       PowderN: sample: Set multiplicity to 1 for lines [0:7]
        (d-spacing 1.94739 is duplicated 8 times)
                                           ...
       Here is the powderN component:
SPLIT 10 COMPONENT sample = PowderN(
    reflections = "Ca.lau", format=Crystallographica, radius = 0.0015,
    yheight = 0.05, Vc = 23.55, sigma_abs = 2.56, sigma_inc = 0.4)
  AT (0, 0, 0.05) RELATIVE slit_beforesample
 
(Vc, sig_abs,sigma_inc are not correct!)

Hi Tom


I don't know if anyone else replied to you already. You have to add the formatting comments to your data file before the reflection lines:


# Format parameters: Crystallographica format
# column_j  4 multiplicity 'j'
# column_d  5 d-spacing 'd' in [Angs]
# column_F2 7 norm of scattering factor |F|^2 in [fm^2]
# column_h 1
# column_k 2
# column_l 3
#
# h   k   l Mult. d-space 2Theta   F-squared


Regards,
Britt

Hi all,
     I put the new Ca.lau file (see enclosure) generated by Crystallographica codes in "C:\McStas\lib\data" and then run a simulation reading Ca.lau for PowderN component.
Unfortunately the system hints as following:
                                                             PowderN: sample: line 271 has invalid definition
                                                                     <mult=0  or   q=0   or    d=0>
                                                                                     ...
                                                             PowderN:sample:File Ca.lau done (0 valid lines.)
     I carefully compared this Ca.lau file with other lau files in the data folder which could be read successfully by my model, but found nothing different in format.
     Could you please kindly tell me what's wrong with it and how to solve this problem? Thank you!
Best,
Tom
