[galaxy-user] Performing operations on tab delimited text files

Hi, My name is Lanelle Edwards. I am a new galaxy user. I uploaded a tab delimited text file to my history. However, the first column of the data I imported is solely chromosome number and start and end position (ALL IN ONE COLUMN) in the format chrI:1000000-2000000. My question is: How can I filter out these values into separate columns using galaxy tools? For example: Having a separate column for chromosome number, column for start position, column for end position. I would really appreciate the help. Thanks, Lanelle Edwards Lab Manger University of Maryland
