Dilating/Padding mask

Current version: v2.15.0+200929

Hello,

I have created a mask in Chimera and imported it into my workspace (as a mask). I am looking to dilate and/or pad my mask. However, whenever I attempt to fill in the required “Threshold” parameter to either dilate or pad the mask, I get this error.

The job will still run, but the mask does not change. Please let me know if this is an error on my end. Thanks in advance!

Hello,

I have realized that this must be set to a number. I think that the wording for this parameter is a bit confusing. Hope this helps someone else!

Hi @Kelly,
You are correct, this value does need to be a number. We will update the parameter description as follows:

The threshold of binarization, within the same greyscale range as the density map itself. For masks, this should be between 0 and 1, but for density maps, this will depend on the greyscale range and can be inspected in UCSF Chimera. This value must be set in order to dilate or pad. Leave blank to skip holes, dilation and padding.
