Hi Melissa, After you use split, there is no a longer a model with both upper- and lower-case chain IDs (since each model is now only one chain) and so the case is ignored. After splitting you would have to specify by model number instead, e.g. #0.25. It is only in models with both upper- and lower-case chain IDs that the case you type matters. Elaine

Hmm. If I have a command file with the following, both chains end up being called smb1_b. Am I missing something? Prior to running this I used the “split” command to separate the chains into sub-models.

setattr m name Brr2_B #0:.B setattr m name smb1_b #0:.b

Hi Melissa, This is already done. Although chain-ID capitalization is ignored when the file has only capitalized IDs, when both are present, the upper- or lower-case that you type is honored. I tested by opening 5GM6, and making sure that the following give different results:

sel :.a sel :.A

Hi- Is it possible to differentiate between chain ID’s that are in upper vs. lower case (i.e. A vs. a) in the command line? Spliceosome complexes have too many chains (ex. 5GM6). Thanks, Melissa
