one can refer to an element or a subset of ten kinds of ICM-shell variables:
| Variable type |
Expression | Result type | Example |
|---|
| string |
string[i] | string | lastChar=str[Length(str)]
| |
string[i1:i2] | string | resName=pdbStr[18:21]
| | iarray |
iarray[i] | integer | CurrSize=sizes[i]
| |
iarray[i1:i2] | iarray | frag=list[4:nitems]
| |
iarray[I_] | iarray | sublist=list[{1,3,5}]
| | rarray |
rarray[i] | real | the=same[i]
| |
rarray[i1:i2] | rarray | all=as[for:iarr]
| |
rarray[I_] | rarray | Part=R1[{1,2,3}]
| | sarray |
sarray[i] | string | best=menu[ibest]
| |
sarray[i1:i2] | sarray | fish=list[4:8]
| |
sarray[I_] | sarray | some=all[{1,2,3}]
| | matrix |
matrix[i1,i2] | real | Element=M[4,5]
| |
matrix[i1] | rarray | atomCaVec=CoordMatr[15]
| |
matrix[i1,i2:i3] | rarray | thirdRow=M[3,1:5]
| |
matrix[i1,?] | rarray | thirdRow=M[3,?]
| |
matrix[i1:i2,i3] | rarray | firstColumn=mm[1:3,1]
| |
matrix[?,i3] | rarray | firstColumn=mm[?,1]
| |
matrix[i1:i2,i3:i4] | matrix | upperSqr=rot[1:2,1:2]
| | sequence |
sequence[i] | string | amino4=bpti[4]
| |
sequence[i1:i2] | sequence | domain=seq[139:302]
| | alignment |
alignment[i] | alignment | column4=globins[4]
| |
alignment[i1,i2] | string | AminoAcIn2ndSeq=globins[4,2]
| |
alignment[i1:i2] | alignment | motif=EFhand[15:27]
| | profile |
profile[i] | profile | His=prof[18:18]
| |
profile[i1:i2] | profile | motif=prf[14:35]
| | selection |
selection[i] | selection | ca18=ca[18]
| |
selection[i1:i2] | selection | frag=ca[14:35]
| | table |
table[i] | table | show t[3]
| |
table[i1:i2] | table | delete t[3:5]
|
Important note. When both lower and upper limits are explicitly
specified, even if they are equal (e.g. list [3:3] ), the type of
the subset object remains the same. If only one element is specified,
the rank may be reduced. The upper limit may be larger than the actual
limit (e.g. t[3:9999]). You may also use 0 instead of the last element
number (e.g. t[3:0]).
