Subject: Nidaq Scanning into a 2D wave
Message-ID: <AM4PR0601MB2068C52E80D829AF669059F696BE0@AM4PR0601MB2068.eurprd06.prod.outlook.com>

Hello List,
I am trying to troubleshoot a problem that has mysteriously appeared in my code. I wonder (perhaps optimistically) if there is a change in behavior in either igor 7 or nidaq tools. I am using the latest version of both as far as I am aware on Windows 7, all 64 bit.

I am scanning using nidaqmx. I have in past been sending the input data into 2D waves (i.e. 100 x 100) that are images. For some reason that I can't get to the bottom of, this no longer seems to work and only the first column of the wave receives information. The other columns are unchanged. If i scan the data into a 1D wave of the correct size (10000) and then redimension it to 100 x 100, then the image is fine.

What I am struggling with is that this code used to work and I can't work out if this is something that I have inadvertently done or if Igor has changed in properties and through some update I have encountered this issue. It is much easier for me to collect data into a 2D wave if possible so would like to continue doing this if I can.

Hope someone can shed light on this.
Thanks
B
Nick
