回复： Read Text row by row, plot them and find the max of its Power spectrum

[Jiabei]

Hi, everyone,

I have to read data from a text file, plot as a time serie and find the frequency to its max power spectrum. I found a previous post related to my issue so I revised his example a little bit. But once I decide to store the data into an array, the Labview reported:' Error 1 occurred at Scan From String (arg 1)'. Can anyone help me out?

Thanks in Advance!

Hi Gab,

the error pops up because the last two lines are empty. I have modified your vi. See the attachment please. Hope it helps.

How come my reply to this in the morning NOT got posted... ?!

Hi Gab,

You can simply insert a Trim Whitespace after the string & get the job done. This is what I posted then.

Again my attachment got missed out.

Guys, thank you all so much!

Finally I used a Trim WhiteSpace.vi to fix this. But Mike's solution is more useful if I want to identify special character from the string.

Regards,

Gab
