Quality control threshold and EPI coverage doesn't show standard deviation

Submitted by David on

Hi,

I just wanted to note, that when using the Threshold motion and EPI Coverage tools it does not show the standard deviation (see pictures attached). What could the problem be and how to fix it :)?

I'm using Windows 7 with Matlab2014a and SPM12 with the latest version of DPABI (V1.3_150710)

greetings

Hi David,

How many subjects do you have? This happens on other datasets as well?

Or could you enlarge the dialog GUI to see if it's just a display issue?

Hi,

thanks for the answer. Surprisingly with other datasets, the SD of the coverage threshold is shown. But preprocessing is the same for all datasets, so I'm not sure what the problem could be. But the SD of the motion threshold doesn't show regardless of the sample I choose. I can't enlarge the window.

I know that with an earlier version of DPABI it sometimes worked with the coverage threshold SD, but I don't know exactly what I did to make it work. The motion threshold SD didn't show in an earlier version of DPABI either, but that's not problem since it is possible to calculate it via the HeadMotion mat-file.

hope this is helpful

Hi,

I wonder if it's the problem of the matlab GUI dispaly in windows. 

You can try to revise w_ThrdCoverage.m

Line 92:     sprintf('( Coverage ) mean: %.4g; SD: %.4g', MeanCoverage, SDCoverage));

to 

    sprintf('mean: %.4g; SD: %.4g', MeanCoverage, SDCoverage));

and see how it displays.

Another way you can try to see if it exist in linux.

Great,

that solved the problem! In this particular group the SD was very small with 0.008163 so this could have been the reason why it didn't show. Maybe rounding up to the 3rd or 4rd decimal number might be useful.

Thank you!

Hi,

That's fine. We can increase the width of the display area in the next release.

Best,

Just wanted to note, that there is the same problem with the motion threshold display which can be fixed in the same way.
