[amrita at iisermohali.ac.in]

Hi,

I have two files having entries like:--
fileA
8  ALA H = 7.85 N = 123.95 CA = 54.67 HA = 2.98	C = 179.39
15 ALA H = 8.05	N = 119.31 CA = 52.18 HA = 4.52	C = 177.18
23 ALA H = 8.78	N = 120.16 CA = 55.84 HA = 4.14	C = 179.93
and
fileB
ChainA: ALA8	-67.217297	-37.131330
ChainA: ALA21	-69.822977	-48.871282
ChainA: ALA23	-59.148095	-46.540043
ChainA: ALA33	-65.459303	-43.269718

i want to join thses two files in such a way that the output file will
contain column of both the files and the enties of similar position of ALA
will be together.so the output file should look something like:----
fileC
8  ALA H = 7.85 N = 123.95 CA = 54.67 HA = 2.98	C = 179.39 ChainA:
ALA8	-67.217297	-37.131330
15 ALA H = 8.05	N = 119.31 CA = 52.18 HA = 4.52	C = 177.18
                                                           ChainA:
ALA21	-69.822977	-48.871282
23 ALA H = 8.78	N = 120.16 CA = 55.84 HA = 4.14	C = 179.93 ChainA:
ALA23	-59.148095	-46.540043
                                                           ChainA:
ALA33	-65.459303	-43.269718
