3.1.3 Playing Back a Series of Data Sets

Starting with Isis version 4.52, Isis has limited support for playing back files

in batches, or sets. An Isis batch file is identified with the file type extension

RUN and contains a list of file types Isis can recognize. When Isis opens a

RUN file, all files in the set play back, one after the other, until all files in the

set have been played or until you have pressed [

End] to terminate the

playing back of these files.

You can also daisy-chain

RUN files. Simply specify another RUN file name

at the end of one

RUN file to reference the next. You can even specify the

current

RUN name to loop a series of files. That is, if a RUN file contains a

reference to a

RUN file, program control will be transferred to the named

RUN file when it is encountered by Isis in the listing. However, you cannot

nest

RUN files (control cannot return implicitly to a RUN file that contains

another

RUN file). This means that if a RUN file contains a reference to

another

RUN file, and there are directory entries beneath the named RUN

file, they will not be played back. For this reason, any reference in a

RUN

file to another

RUN file should always be placed at the end of whatever

RUN file contains the reference to the second RUN file.

The principal reason for using Isis batch processing is related to mosaicking.

Batch processing in Isis gives you control over the order of files that you intend

to play back when you make a mosaic, rather than relying only on the order in

which you recorded your data during your survey operation. Specifying the

order can be important if you anticipate that some of your imagery in earlier-

recorded

lines may be masked or occluded by overlapping imagery occurring in

later

recorded lines.

For example, consider the contents of this

RUN file:

Furgbump.XTF

wallsnip.XTF

rundat.RUN

If you played back this file in Isis, after Isis finished playing back

Furgbump.XTF and wallsnip.XTF, program control would transfer to

rundat.RUN. Furthermore, if the name of this RUN file was the same as the

batch file that began this playing back these files (in this case,

rundat.RUN),
