it cannot open the file .. possible causes:
1) the file is not in the directory where script is running as you have no path to file in command in must be in current directory
2) the file name is incorrect .. if windows check the extensions, e.g. file not BM68elx.acc.txt or something
3) file permisions dor that file do not allow you to open it.

Thank you fmk! I found that if I want to use the "BM68elx.acc" , I must change the digital matrix of this file's content(download from the "opensees Examples" ), just like become X*X to X*1. How can I change the matrix? Use "READSMDFILE"?

the ReadSMDFile just contains tcl code to open, read and write some files. You simply midofy it to suit any format you want. you just need to understand a little tcl to do so. i suggest you try as it will make you a better user of the program
