How to copy text content from a .txt file to a .ats file?

Currently, I can only generate a txt file by fprintf(). Then I have to copy and paste the content from the txt file to a .ats. I tried fprintf() directly to a .ats file or copyfile() to a .ats file, but seems the format is incorrect although the file extension is .ats. Any suggestions? I am thinking about create a empty .ats file and copy the text content to the clipboard and then copy the content to the ats file. Is it doable? Or any better solutions?

Just wanna let you know. I resolved this issue by using

fid=fopen(filename,'wt')

Instead of

fid=fopen(filename,'w')
because the *.ats file requires the ending character of a line to be '\r\n'.
