HI Michael, Chimera is no longer actively developed and those who wrote the RR Dist Maps tool are no longer with the group, sorry. Unfortunately, it does not have a corresponding command either.

Hi, I played around a bit with the nice RRDistMaps tool in Chimera v1.17.3 and I am wondering why the output .png plot's size of a single protein structure analysis doesn't correspond at all to the protein length? For a 659 amino acid long protein I was expecting to find a plot in which the distance matrix data area is sized 659 by 659 pixels (or multiples of this) to allow for placing the corresponding grey-scale value for each calculated distance as indicated in the plot's legend. Instead, it appears that the output image's dimensions are actually dynamically adjusted depending on the RRDistMaps's tool window size at the time of generating the plot. As a result, the core data region in the plot can barely accomodate the full data set with regular screen resolutions - at my end at least, it is always smaller (except maybe for very small proteins; I did not check this in more detail, yet). Playing with the sliders and trying to re-export those manually re-formatted images also doesn't seem to solve the problem. Did I miss something here? I just found out about this accidentally while writing a small Python program analyzing the output plots pixel-wise. ;-) I also noticed that the data area appears bordered by a triple line set (single pixel wide, each: grey-black-grey). Please note that I don't question the numeric distance data as exported in .csv/.tsv format - it's all just about the exported .png file.
One additional question: Is it possible to run this tool in batch mode from the command line with parameters specifying (forcing) the (correct) output plot size (data region), the input .pdb structure file and all the options available in the GUI plus export the distance data table in .csv format (and maybe even the alignment data)?
And finally, it appears that I encontered a possible bug when trying to process more than two sequences using RRDistMaps: The Muscle-based online alignment seems to fail (tried it for two days now) - here is the log:

Typically, if you get a TypeError, it's a problem on the remote server and it should be fixed shortly. If you get a different error or get TypeError consistently for more than a day, please report the problem using the Report a Bug... entry in the Help menu.
