how to rename bunch of files

Hi experts,

I have 277 Image files ,like

zROI1FCMap_Sub011.img, zROI2FCMap_Sub011.img, zROI3FCMap_Sub011.img ..... zROI 277 FCMap_Sub011.img,

now I want to rename this to

zROI*218*FCMap_Sub011.img, zROI*219*FCMap_Sub011.img zROI*220*FCMap_Sub011.img...... zROI*494*FCMap_Sub011.img

Could any one please tell me how to rename?

Thank you

You will have literal asterisks in your file names? That is possible, I guess, but it would likely tend to mess up anything that does wild-card processing.

Hi Walter, there are no asterisks in my file name, I just wanted to highlight the number which I wanted to rename so made it BOLD.

Thank you

You need to put a space before the first asterisk and a space after the second asterisk to make it bold, like I did for your first one (which I edited). Though, that also puts in spaces in addition to making it bold. I'm not sure how to make it bold without having spaces in the output.

Hi Thanks a lot for your answer, I have one more doubt, that is since I have the file names from 1 to 277 in 1,2,3,4,...277 fashion, I think the matlab reads it as 10,100,101,...109 Could you please help me how to overcome this problem

with best regards

So use sprintf() or num2str() to convert the number the way you want it.

[Image Analyst]

Use two numbers (%n.nd) to pad your number with zeros and keep 10 right before 11 (actually 010 right before 011) rather than right before 100 like it normally would:

baseFileName = sprintf('zROI1FCMap_Sub%3.3d.img', imageNumber);

Note the %3.3d in the format string.
