!!!!! SUPERSEDED by bugfix.56 !!!!!!

Programs: carnal

Severity: moderate

Problem:  Fails to read pdb files with lines < 80 chars.


Fix:  Make the following change to src/carnal/util.c
-----------------------------------------------------------------------
=== If bugfix.39 was installed:
*** OLD util.c
--- NEW util.c
485c485
< 	if (fgets(scanbuf, 80, file) != 1)
---
> 	if (fgets(scanbuf, 80, file) == NULL)
-----------------------------------------------------------------------
=== If bugfix.39 was not installed:
*** OLD util.c
--- NEW util.c
***************
*** 482,488
  {
  	int	c;
  
! 	if (fscanf(file, "%80c", scanbuf) != 1)
  		return(-1);
  	scanbuf[78] = '\0';
  

--- 482,488 -----
  {
  	int	c;
  
! 	if (fgets(scanbuf, 80, file) == NULL)
  		return(-1);
  	scanbuf[78] = '\0';
  
***************
*** 501,511
  	if (sscanf(scanbuf+46, "%12f", &xyz[2]) != 1)
  		return(-2);
  #endif
- 	while (1) {	/* skip to eoln */
- 		c = getc(file); 
- 		if ( c == 10  ||  c == EOF)
- 			break;
- 	}
  	return(0);
  }
  

--- 501,506 -----
  	if (sscanf(scanbuf+46, "%12f", &xyz[2]) != 1)
  		return(-2);
  #endif
  	return(0);
  }
  

-----------------------------------------------------------------------

Temporary workarounds: pad out lines in pdb to >= 80 characters.
