OK, I see. Right, now I understand the $ business -- these are PhP
substitutions. I see you need to identify these atoms by standard RasMol
format. That changes everything! You can't do this:
measure @a @ b
where a = "39:A.CA/1.1" and b = "40:A.CA/2.1"
what you have to do instead is create the entire measure command as a
string and then execute it, like this:
script inline @{"measure {" + a + "} {" + b + "}"}
Minor comment: I would put the set and font commands earlier, out of the for
loop; no need to repeat those.
If you have a reference atom and then a list of atoms from different models,
I think the function would be this, provided you create an array of strings
that look like ["35:a.ca", "36:b.ca","36:b.ca",...] that has the reference
atom in position 1, and the target atoms in :
function crossMeasure(atomList){
var n = atomList.length
measures delete
set measurementUnits angstroms
set measurements 3
font measure 16 serif bold
for (var i = 2; i <= n; i++) {
script inlne @{ "measure {" + atomList[1] + "/1.1}{" + atomList[i] +
"/" + i + ".1}" }
}
}
Or maybe, if the homology models all have the same group, just:
function crossMeasure(atom1, atom2){
var n = atomList.length
measures delete
set measurementUnits angstroms
set measurements 3
font measure 16 serif bold
for (var i = 2; i <= n; i++) {
script inlne @{ "measure {" + atom1 + "/1.1}{" + atom2 + "/" + i +
".1}" }
}
}
