Hi all,
I am writing a batch processing routine in order to do some querying.
Steps:
1) Read in 30 images ( could be 60 or more..hence using batch)
Since i am using a file_search method to read in all the files, i want
each file to be given a unique name or ID because i need to compare
them with each other. So, instead of reading in 30 files separately
and assigning variable names to them, i want to do it automatically
using a counter in a loop or something like that.
Eg: if i=0 and numfiles=30,
i want to name the first file thats read b1, second file b2, third b3,
30th as b30.
Once these are named, i want to be able to compare b1 to b2 or b3 to
b5 etc.
So, its not just about naming these files since that can be done with
a strmid function.
my idea was something like
names=file_search(*.img,count=numfiles)
while i lt numfiles
b[i]=names(i)
I have tried it and it says b is not defined. I am guessing i cannot
name variables dynamically.
I don't know if i am very clear about my problem.
Basically, i want to be able to assign unique variable names to each
file thats read so that i can use those unique IDs to query and
compare.
Any ideas ? i can give more information or try to be clearer about my
problem if necessary.
