I've got to extract some numbers from a file that are in lines of text. Since the line contents are not numbers, I presume I must pull the line out as a string. Here I start by pulling out just one line:
inFile = OpenRead["197-tst.txt"]
y = ReadList[inFile, String, 1, RecordLists -> True]
Close[inFile];
This appears to pull in a line. Now I want to take characters 25 to 110 to get just the stuff I want:
y1=StringTake[y ,{25,110}];
Here's the output. StringTake doesn't seem to work.
StringTake[{aEX-004 2002197 0 0 0 5935.80 5946.66 27.06 -1281.9 -229. 321. 317. 367. -115. 126. 146. -410. -426.000000EF 75.}, {25, 110}]
It doesn't take loading another package as far
as I can tell from the help. I'm thinking that it doesn't work because it's trying to work on a list
rather than a string. I've tried Flatten, and other stuff to try to get to just a string and not a list but
nothing has worked so far. I'm a long way from getting to those numbers in there but heck, I
can't even get to the string. Can anyone point me in the right direction?
Thanks, Rob
