Please add any tips or tricks to this page. We can gather them all up and organise them into a more formal how to later.

To view the properties dialogue window, right click on the analysis item.

In the properties dialogue window, if you can't see all the help text in the middle try making that section bigger by dragging the divider above the text upwards.

If you want to run analysis tree on several images, each with independant results, open the images as individual images. If on the other hand you want to analyse one thing going through several images, for example slice sensitivity profile for CT, then load all images into a single multi-layer image:

NOTE When loading several or large images, especially across a network, there can be a delay once you have made this choice. Please wait, the images are being loaded!

Below are a number of tips and tricks that were discussed at a recent IQworks South West User Group Meetings

• Save a tree before closing the image or the tree does not save.

• Do not use an image that has been flipped or altered. This process leads to interpolation of pixel values and the analysis will not work.

• Use only DICOM images in IQworks- JPEG images will not give correct results.

• When opening an image, once the correct image has been chosen untick the ‘show preview’ box before opening the image. Further images can then also be opened this way without the software crashing.

•When calculating MTF set the ‘sample parameter’ to 0.1. This gives results that are comparable to those calculated from MatLab?.

•To produce a .csv file select csv in the report generator and click ‘store data now’ before generating the report. (some people have noted that the software asks if you require the file to be saved but for other users this is not the case)

•The stack profile analysis function only works with a rectangular ROI.
