Coding in TOF Neutron Diffraction CodeDate: Mon, 20 Sep 1999 17:49:28 +0100 (BST) From: Jon Wright [[email protected]] To: RIETVELD_L Distribution List [[email protected]] Subject: Re: RIET: TOF Neutron Web based programming resources? Lachlan, You can get hold of the freely available CCSL code from your site and compile programs tf112m etc for doing TOF neutron Reitveld fits with magnetism too! Compiles with the free g77 compiler after some minor changes. All code is there, I have compiled and run it on a PC and presented the ensuing results at IUCR and ECNS, although only one person seemed to notice. It is the old ral code from about 1995. Does pattern simulation as well as refinement. Cheers, Jon |

To compile the ccsl program you need to edit it slightly, as described in the source. Subroutine OPFILE (lines 976-1002) wants to end up only containing: (Note this means losing the RECL and ACCESS statements.) OPEN (N,FILE=FILNAM,STATUS=STAT) RETURN END Also line 699 appears to need an alteration... from: IF ((LINE80(1:9) .NE. ' END') .OR. (LINEND(LINE80,1,80) to: IF ((LINE80(1:9) .NE. 'C LEVEL') .OR. (LINEND(LINE80,1,80) in order for the split part of the program to work? (eg: g77 ccsl.f -o ccsl) Ignore the warnings. Then create a file ccslda.dat, as described in the readme file. Using the ccsl mode of the program (so the first line of ccslda.dat is CCSLA) you need to extract the lib, pr, pf and pma parts of the code. Assuming the file mistre.ss sits in your current directory then run ccsl and give the following responses: l,ill,lib,mk4,mistre.ss,return,n,return A file called libmk4.f should have been created. Repeat the above but substituting pr etc for lib. This will get you the files prmk4, pfmk4 and pmamk4.f You then need to split these into individual subroutines (otherwise the compiler gets really upset). I do this by creating a directory called lib and putting a file in it called ccslda.dat containing: SPLIT .. MK4 LIB Then cd into the lib directory and type ..\ccsl. Give the extension as "for" and you will receive lots of fortran files. They can be compiled with the following: g77 -c -fno-globals -Wno-globals -finit-local-zero -fno-automatic *.for The globals flags suppress warnings, the others suppress bugs, I think. It will choke on nopfil.for - comment out lines 200-249 except for 242 and 243, the only open you want is: OPEN (UNIT=LUN,FILE=NAMFIL,ACCESS=FILACC(IA),FORM=FILFOR(IF), & STATUS=FILSTA(IS),ERR=52,IOSTAT=IOE) Also initil.for needs changes. Either get rid of the call to time (line 239) or alter the mistre.ss file so that TIM is declared as an 8 member array instead of 5 (you'll need to extract everything from the mistre.ss again if you do this). Also IPOPE.FOR needs a change. I use the following data statement to sort out file opening errors (you can leave it alone and never overwrite old files): DATA NERR,NSWI,IOS/3, 1,2,0,0, 2,128,126,127/ Repeat the process for the pr and pf sections of the library. eg. directories pr and pf and change LIB to PR or PF in ccslda.dat. Changes needed in order to compile are: pr/rfacpr.for: Add declaration LOGICAL LATABS pr/inrfpr.for: Alter to format statements on lines 396 and 397 as the compiler error message suggests. pr/calprm.for: Add declaration LOGICAL LATABS A library can then be created with: C:\ccp14>ar -ru libccsl.a lib\*.o pr\*.o pf\*.o C:\ccp14>ranlib libccsl.a Now alter ccslda.dat to contain: "GET,.,MK4,PMA" and run ccsl. Type tf12ls then return and you should have a file tf12ls.got which contains the source for this program. Rename it to tf12ls.f and edit it to avoid a g77 bug. It needs to contain.... DIMENSION ALSQ(3000) CHARACTER *6 G77NAM C% C MATSZ=%MATS% MATSZ=3000 G77NAM='TF12LS' CALL FORTY(G77NAM,ALSQ,MATSZ,PCTF01,PFTF02,DUMMY,CALPR) Essentially you can't pass 'TF12LS' as a literal into FORTY, although you should be able to (Ken Shankland got me past this problem). Then compile with the same flags as above and link with: C:\ccp14>g77 -fno-globals -Wno-globals -finit-local-zero -fno-automatic tf12ls.o libccsl.a -o tf12ls That's it! I ran through this as I typed it and just tested it on some files from the RAL vax cluster: hrpd$disk0:[hrpd.calib]si_197.ccl hrpd$disk0:[hrpd.calib]si_197.dat It appears to work: C:\ccp14>tf12ls Give name of Crystal data file si_197 Give name of Observations file si_197 >>> Starting cycle 1 Chi squared = 1.1867 for 7093 observations and 16 basic variables >>> Starting cycle 2 Chi squared = 1.1866 for 7093 observations and 16 basic variables >>> Starting cycle 3 Chi squared = 1.1866 for 7093 observations and 16 basic variables Give name for New Crystal Data file si_197 >>> Starting cycle 4 Give name for File to output Profiles si_197 Chi squared = 1.1866 for 7093 observations and 16 basic variables Look at the manual which is linked to the hrpd web page for information on running the program. Note that by extracting the library with the 'ill' option it will always prefer files with extensions .cry for crystal data files and new files will overwrite old ones. (The ral option chooses to read .ccl files and write .ccn files). Using the GDB debugger is problematic - to get anywhere at all you cannot open scratch files, so just remove the STATUS='SCRATCH' specifier in NOPFIL. It's a bug in g77/gdb/windows - dunno which. Debugging is a pain in general but adding -fdebug-kludge helps. Peak shapes and peakcentres are in the pf section, which is probably what you are after. It's called pfcn03 and it gives an alternative chunk of source code the low angle asymetry described by Finger et al. Some of the programs also do Pawley fits.
