This is the guide for programs and tables for modulated structure analysis, which is available via http (http://quasi.nims.go.jp/yamamoto/).

Programs for Modulated Structures

All the programs use the i/o routine package remosio. The last three programs use the subroutine package calcomp, which simulates the plotter subroutine package of Calcomp Co Ltd. These are the Fortran and C source codes. There are two versions, one for UNIX and the other for Vax VMS. The latter is written only in Fortran. If you have some problem for the link of the Fortran and C programs in the UNIX version, please try VMS version.

For downloading, press download QUASI06_mac.01_05 Mac OS 10.4(Tiger) version(last modified Jan. 05, 2006) (25Mb)

For publications using the program lodemac, the following paper should be cited. H. Takakura, M. Shiono, T. J. Sato, A. Yamamoto, and A. P. Tsai, Phys. Rev. Lett. 86 (2001) 236-239. For other programs, A. Yamamoto, Acta Cryst. A52 (1996) 509-560 should be cited.

Requirement for computers: For all programs except for qcmem, a computer memory larger than 512MB may be necessary. For qcmem, a memory larger than 1GB or more will be needed. If you have "Segmentation fault" error message, more memory size may be necessary. All the programs are terminal_based. In Mac, you can run these programs in Terminal, while in Windows, you can use command prompt instead. For their installation and usage, read README file. (All the files are in a compressed tar file.)
