Extend the beginning or end of traces
S-01616
As a Tullow Geophysicist I want to add additional samples to the start or end of my trace. I want this because I frequently perform these extensions (11th most popular).
PreDev Notes:
Dev Questions:
- Are the values for samples added to the traces within trace (i.e. Trc_i.resize(ns+n); Trc_i[0:n] = constant ) or are they functional (i.e Trc_i[0:n] = f(j)) or random?
- Are the values for samples added to the traces the same from trace to trace (i.e. Trc_0[0:n] = c ; Trc_1[0:n] = c; ... Trc_N[0:n] = c) or do they vary from trace to trace (i.e. Trc_0[0:n] = c0 ; Trc_1[0:n] = c1; ... Trc_N[0:n] = cN)?
- Or is it all of the above?
- Is this an operation where the number of samples in a SEG-Y file is increased so files can be concatenated?

Success Criteria
-
The binary header value ns is updated when extending the trace length. -
A file whose trace length has been extended should be able to be concatenated with files that have traces of the new length not the old length
