This may not be the most elegant solution but you can try using parameter files. Here is an example:<\/p>\n

    \n
  1. Create some data.\n
    <\/i>
    <\/i><\/a><\/div><\/div>
    Flow('data',None,'spike n1=100 | bandpass fhi=40')<\/pre><\/div>\n<\/li>\n
  2.  Generate a parameter file from it.\n
    <\/i> 
    <\/i><\/a><\/div><\/div>
    Flow('mag.par','data',\"attr want=max | sed 's\/value = \/mag=\/' \")<\/pre><\/div>\n<\/li>\n
  3. Use the parameter file in processing.\n
    <\/i> 
    <\/i><\/a><\/div><\/div>
    Flow('test','mag.par','spike n1=100 par=$SOURCE',stdin=0)<\/pre><\/div>\n<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
