Hi!<br><br>You could try somthing like:<br><br><span class="il">awk</span> '{ print "streamtrack <therest_of_the_command>" $1 " tract_output" }' list_of_the_coordinates.txt | sh<br><br>This command runs throught the list of your coordinates (=per subject, as described below, saved in a txt file), executing each time the streamtrack command (please complete your command within the <>)<br>
<br>Hope this helps!<br>Markus<br><br><br><br><div class="gmail_quote">2012/4/20 Luis Concha <span dir="ltr"><<a href="mailto:lconcha@unam.mx">lconcha@unam.mx</a>></span><br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
Hello.<div><br></div><div>I would like to seed from several very specific seeds that I normally pass to the -seed option of streamtrack as x,y,z,radius. However, I must pass them one by one, by several invocations of the command. Is there a way to pass a text file for seeding, which could contain the coordinates? (I'm thinking of a file with nRows=nSeeds, and 4 columns [x,y,z,radius]). </div>
<div><br></div><div>Also, I need to be able to keep a good order between the tracks and the seeds, so I would expect the track indices to be the same as the rows in the seed text file.</div><div><br></div><div>So far I have been using a for loop, making several track files, but I imagine (and please correct me if I'm wrong) that the bottleneck for processing speed is in the loading of the CSD file at each iteration.</div>
<div><br></div><div>Any suggestions are most welcome. Thanks.</div><div><br></div><div><br clear="all">Dr. Luis Concha Loyola<br>Instituto de Neurobiología<br>Laboratorio C-12<br>UNAM, Campus Juriquilla<br>Boulervard Juriquilla 3001<br>
