Dear Yung-jin,

❝ I see. I think you're talking about NCA output. You first did NCA and saved the output file. Then load this NCA output when you planned to do GLM. The error occurred at this moment.


Exactly! I must confess, my description was not a proper bug report...

❝ You have proposed a very nice way to fix this problem. Yes, we will try to make if more flexible. Does a user know what these options for?


No idea. Sometimes I believe, that anybody in doing PK should now about how his/her file's content. But on the other hand, importing a file with field sep ';' and dec '.' also isn’t straightforward as one might think (e.g., in WinNonlin):

Open -> Filetype ASCII Data (*.dat;*dta;*.prn;*.csv) -> oops, everything in the first column…
Ah, there's an Options-button, hhm, select X Automatically determine file options -> same result…
Next try: Field delimiter ;… working, but header in first row, etc.
WinNonlin has no option to select the decimal separator anyway.

Of course there are combinations which are impossible to resolve, e.g. the file nasty.csv:
x,y
1,2
1,5,2,5
where in the third row every import routine will end with an error. No program can 'guess', that it was produced with a badly configured German Excel (the two numbers 1.5 and 2.5) were meant...
If we change nasty.csv (assuming a German Excel) to:
t;c
1;2
1,5;2,5
WinNonlin would read in the file, but treat the third row as plain next.
Writing =A1+5 to cell C1 we get 6, but for =A2+5 in cell C2 we get #VALUE!...

❝ or still we are going to get lots of e-mails, anyway? :-(


Hard to tell. I wouldn’t bother too much about making the input routines 'foolproof', but invest a little effort in the help files telling which format is acceptable – and which one is not.
