How can I load such a long data in labVIEW and convert it from string to array

[dec04009]

Dear all

I met with a problem when inputing data to labVIEW

When I try to load a data, which size is 4(columns)*77900(lines) as shown in attahed file, the labVIEW

did not response, How can I deal with it?

After loading it, I should convert it to array, what should I do

Please help me

Try this in 7.0 format.

Thank you for replying

it works well, but always the size of the data is not known, so it is another problem.

I try to load the files in other ways but it cost a lot of time.

Any more advice?

I try to use "read from spreadsheet files", but only the first column is recognized

The line separater is "\s", I try to replace it with "\t", which means the "tab", but for

such a large file, the repacement seems impossible since the computer did not

response for a long time and I have to restart my computer

Try this. It reserves a large memory area and then reshapes the array after it reaches the end of the file.

This one is better. It just reads the file and makes it a 2D array of DBL.

Thanks a lot

It woks well, it is interesting to replace the double space with a sigle space

It is not very convinent in labVIEW to restrict the line separater

Many thanks!
