wig file change span from 150 to 300

Question

[Saad Khan]

Hi

I have a number of wiggle files some of the wiggle files have span size of 300, others have span size of 100,200 and or 150. All these wig files represent disparate sources of data. I want to convert all these wiggle files to 300 bp region. Is there a way I can do that for files with 150,100,200 span size.

Thanks
