In order to exclude the contents while reading from the
sequential file stage we have to use the filter option.
There we have to specify the unix command:
Sed -e '1d' -e '$d' <filename>

In sequential file stage use the filter in the options
In filter use sed '1d;$d'
You can use sed '<start>,<end>d' to delete particular rows and use sed -n '<start>,<end>p' to keep particular rows

Answer / shiv
Sreenu is also right, but we have another option as well.
Use head and tail stages in datastage like this:
Seq_File-->Tail_stage--->Head_Stage---->Dataset(Target)
in this way first u can exclude the first record using tail specify 999 record in tail stage, then u can exlclude last record by using head stage.(998 top records).

Well if must use filter option in sequential stage then
the Ans is:
head -n 10 'FileName' | tail -n 8

suppose if ur file has 10 records + column name then total
lines are 11.

tail -n 8 will fetch 2 to 9 records excluding colname and
1st record.
