n\#out is equivalent to n\#, both of them overwrite end\#.
int | beg#=0 | the number of zeros to add before the beginning of #-th axis | |
---|---|---|---|
int | end#=0 | the number of zeros to add after the end of #-th axis |
pad increases the dimensions of the input dataset by padding the data with zeroes. Here are some simple examples.
bash$ sfspike n1=5 n2=3 > one.rsf bash$ sfdisfil < one.rsf 0: 1 1 1 1 1 5: 1 1 1 1 1 10: 1 1 1 1 1 bash$ < one.rsf sfpad n2=5 | sfdisfil 0: 1 1 1 1 1 5: 1 1 1 1 1 10: 1 1 1 1 1 15: 0 0 0 0 0 20: 0 0 0 0 0 bash$ < one.rsf sfpad beg2=2 | sfdisfil 0: 0 0 0 0 0 5: 0 0 0 0 0 10: 1 1 1 1 1 15: 1 1 1 1 1 20: 1 1 1 1 1 bash$ < one.rsf sfpad beg2=1 end2=1 | sfdisfil 0: 0 0 0 0 0 5: 1 1 1 1 1 10: 1 1 1 1 1 15: 1 1 1 1 1 20: 0 0 0 0 0 bash$ < one.rsf sfwindow n1=3 | sfpad n1=5 n2=5 beg1=1 beg2=1 | sfdisfil 0: 0 0 0 0 0 5: 0 1 1 1 0 10: 0 1 1 1 0 15: 0 1 1 1 0 20: 0 0 0 0 0You can use sfcat to pad data with values other than zeroes.
