rename file
Hi,

I have files in the format

Code:
thread_1_seq_1965.440.755943413
thread_1_seq_1966.577.755943443
thread_2_seq_2034.383.388388888


I want to rename this in the form of
Code:
1_1965.arc
1_1966.arc
2_2034.arc

Discard everything except the [8-9] th char and [14-17]. The character position remains the same.

How can i do this using awk/sed or any other command
